Forthe given scenario, determine the type of error that was made, if any. (Hint: Begin by determining the null and alternative hypotheses.)A cell phone company claims only $50 as the mean amount its customers spend on cell phone service per month. One skeptical consumer claimsthat the mean amount its customers spend on cell phone service per month is greater than $50. The skeptical consumer conducts a hypothesis testand fails to reject the null hypothesis. Assume that in reality, the mean amount its customers spend on cell phone service per month is $58. Was anerror made? If so, what type?

The question is about errorsIntroduction :There are two types of errorsType I error :Rejecting the…

Answered: For the given scenario, determine the…

A health provider saw that 48% of their members received their flu shot in recent years. The health care provider tried a new advertising strategy the following year, and they took a sample of members to test if the proportion who received their flu shot had changed. Determine the null and alternative hypothesis
A textbook publisher claims that 75% of college students enrolled in a course that uses their textbooks pass the class. One professor thinks the proportion is actually higher. He surveys 111 students in classes that use a textbook from the textbook publisher and finds the 92 of those students ultimately pass the class. Perform a hypothesis test using a 4% level of significance. Step 1: State the null and alternative hypotheses. Ho: ?v?v Ha: ? ?v (So we will be performing a Select an answer v test.) Step 2: Assuming the null hypothesis is true, determine the features of the distribution of point estimates using the Central Limit Theorem. By the Central Limit Theorem, we know that the point estimates are Select an answer v with distribution mean and distribution standard deviation Step 3: Find the p-value of the point estimate. P(? v ? v = P(?v?v p-value = Step 4: Make a Conclusion About the null hypothesis. Since the p-value = = a, we Select an answer v the null hypothesis. O We cannot…
A claim is made that the proportion of college students who have Netflix accounts is 0.92. Mateo believes this claimed value is too high. He is able to survey a random sample of 180 college students, and he finds that the sample proportion who have Netflix accounts is 0.88. Mateo proceeds to use this data to conduct a hypothesis test. Based on this information, which one of the following statements is correct? The P-value will be smaller than 0.01 but larger than 0. The P-value will be between 0.01 and 0.05. The P-value will be between 0.05 and 0.10. The P-value will be larger than 0.10. The P-value will be negative.
2005 9.135 Kicking the cigarette habit. Can taking an antidepressant drug help cigarette smokers kick their habit? The New England Journal of Medicine (Oct. 23, 1997) published a study in which 615 smokers (all of whom wanted to give up smoking) were randomly assigned to receive either Zyban (an antidepressant) or a placebo (a dummy pill) for six weeks. Of the 309 patients who received Zyban, 71 were not smoking one year later. Of the 306 patients who received a placebo, 37 were not smoking one year later. Conduct a test of hypothesis (at a = posed in the first sentence of this exercise. 9.138 .05) to answer the research question
A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal was 71%. Suppose that we have reason to believe that this proportion has changed, and we wish to carry out a hypothesis test to see if our belief can be supported. State the null hypothesis H0 and the alternative hypothesis H1 that we would use for this test.

A golf instructor claims that more than 70% of his students have improved their driving distance by at least 20 yards after viewing and applying the techniques described in his instructional video. If 138 out of 180 viewers say that their driving distance has improved by at least 20 yards, is the instructor's claim valid? Identify the null and alternative hypotheses for this scenario. Is the instructor's claim that "more than 70% of his students have improved their driving distance by at least 20 yards," valid? Your response should include your decision and conclusion in context of the scenario.
