Steps in Hypothesis Testing Essay Example for Free

Steps in Hypothesis Testing Essay My research topic is a correlation study between quantity of water intake and number of sleeping hours for humans. I became interested in the topic when a friend of mine shared an interesting belief of his culture that drinking too much water can upset sleep. Although this is not the exact topic that I am choosing for this study, I believe that the groundwork for that research interest is to determine whether or not the average number of glasses of water that a person drinks in a day has any relationship with that person’s average number of sleeping hours. This is data that can be collected through a survey of at least 30 respondents to make the sample large. In following the 5 steps of hypothesis testing, my null hypothesis would be that there is no significant relationship between the average number of glasses of water consumed in a day and average number of sleeping hours (H0: Ï = 0) (Lane, 2007). This implies that my alternative hypothesis is that there is a significant relationship between the said variables (H1: Ï Ã¢â€°   0).The hypothesis will be tested at a 0.05 significance level. The statistic that will be used is the Pearson r correlation coefficient which will be computed using appropriate statistical software. Its probability value will be determined and compared against the 0.05 confidence level. If the probability value exceeds the confidence level, then the null hypothesis is accepted, and we can conclude that there is no significant relationship between the average number of glasses of water consumed in a day and average number of sleeping hours. If the p-value is less than or equal to the confidence level, then the null hypothesis is rejected in favor of the alternative hypothesis.   Reference Lane, D. (2007). Steps in Hypothesis Testing.

Richard Marcinko :: essays research papers

Richard Marcinko A brilliant virtuoso of violence, Richard Marcinko rose through the Navy ranks to create and command one of America's most elite and classified counterterrorist units, Seal Team Six. Then Marcinko was given orders to create Red Cell, a team of the best counterterrorists, whose job was to check the security of the military's top installations. Richard Marcinko was the ultimate rogue warrior.   Ã‚  Ã‚  Ã‚  Ã‚  First, born Thanksgiving Day, 1940, Marcinko was from a poor, broken home. He was always very independent, having a paper route at five and cutting school classes regularly. At the age of fifteen, he got a job at a local restaurant. At the age of seventeen, he quit school and joined the Navy. After two years as a teletype clerk, he convinced his Commanding Officer to send him to UDT, Underwater Demolition Team, training.   Ã‚  Ã‚  Ã‚  Ã‚  Later, in June 1966, he joined Seal Team Two and went to Vietnam. He served two tours there and came back a decorated war hero. After his return to the United States, he became Commanding Officer of Seal Team Two, where he served for eight years. Then, he came up with the idea of the Navy's first counterterrorist unit, Seal Team Six.   Ã‚  Ã‚  Ã‚  Ã‚  Now, the most important contribution Richard Marcinko made was his idea of Seal Team Six. Seal Team Six was created as part of the CounterTerrorist Joint Task Force, a group which includes one elite unit each from the Navy, the Army, and the FBI. Marcinko was given permission and unlimited expenses from the Pentagon to create this highly elite group. He was then named Commanding Officer of Seal Team Six, which he served as for three years. This elite unit has went on classified missions from Central America to the Middle East, the North Sea, Africa, and beyond. Then Marcinko was given orders to create Red Cell. Red Cell's job was to check the security of the military's top facilities and installations. It was made up of the twelve best counterterrorists in the world. After going to several facilities and proving the security was terrible,

Effects of Deforestation

Tropical rain forest is very important for our nature such as for ecosystem balance, earth temperature and flora and fauna habitat. In our country Malaysia, most of the forest are announced as a forest reserve to preserve our forest from destroyed. Not only important to flora and fauna but also to people. For some people, their lives depends on forest. However, deforestation activity by irresponsible people has led to imbalanced ecosystem. First of all, the effect of deforestation is pollution especially water pollution. This problem occurred when people often cut down the trees illegally. So, there are no roots to hold and prevent the soil from fall down. The soil that does not have roots to hold it can easily fall down into the river. Consequently, the water becomes polluted. Cloudy and shallow. From this, the aquatic life ecosystem will be threatened and damaged. Another effect of the deforestation is flora extinction. As we all know, forest is the habitat of most species for flora. For instance, raflesia, nepenthis, ferns, and various kinds of wood. The loggers who cut down the trees do not care whether the kind of trees is mature or immature. As a result, the trees which is flora habitat will be damaged. The flora will die and extinct due to this problem. Finally, we can see clearly the bad effects from deforestation. If this problem still happen, our forest will be damaged and vanish. In that case, our next generation will not have a chance to know all these valuable flora. So that, government and people should work together to overcome this problem.

The Third Man By Richard Rodriguez - 1478 Words

The small city of Brownsville is small in both population and mind. Even though there are individuals who commute morning and night from country to country, there is no unity. Growing up, I had never experienced a â€Å"diverse† city. In the city of Brownsville, Hispanics are the majority. As a result, individuals who saw somebody of a different race or ethnicity would make negative and offensive comments towards them. At times, these offensive comments were accidental. Other times, the offensive comments were on purpose and intended to appear humorous to friends. Apart from discriminatory remarks to outsiders, this happened amongst people of my Hispanic community. Richard Rodriguez, author of Brown: The Last Discovery of America, tackles†¦show more content†¦One day in the 1960s, the success of the Negro Civil Rights movement encouraged Hispanics (along with other groups of Americans) to insist on the coveted black analogy, and thus claim the spoils of affirmative action. The â€Å"coveted black analogy†, which Rodriguez states that Hispanics â€Å"insist[ed]† on, can be viewed as an acknowledgment to the suffering that African Americans experienced. Due to this struggle, African Americans were one of the primary groups that affirmative action was meant to help. As a result, Rodriguez implies that by seeing the benefits that African Americans were receiving, Hispanics wanted to be included as well. In Rodriguez’s perspective, this led Hispanics to â€Å"claim the spoils of affirmative action† even though they were not the group that affirmative action was initially geared toward. Overall, the chapter, which focuses on â€Å"Hispanicity†, impacted me because I began to formulate ideas which opposed those that had been hammered into my mind all my life. For so long I had heard that minorities were victims to oppression by whites and for that reason minorities should strive to do more than what is expected from them. In reading Rodriguez’s claim, questions that had never been explored in my development arose in my mind such as â€Å"Are Hispanics really the victims?†, â€Å"Do Hispanics truly strive to their fullest to accomplish things that have never been done?†, and lastly, â€Å"Are Hispanics committing acts of hypocrisy?†.
