It has been reported by a university's president that 60% of the students are using their cell phones during class to text their peers. A professor wants to see if her students are using their cell phones less frequently than the general population. The professor surveys the students and asks them to report the number of minutes they use their cell phones during a day at the university. Open the Excel file "cell phone use" and using SPSS, conduct a t-test to test the professor's assumption that her students will use their cell phones significantly less frequently than the general population at the university (alpha = .05). Write the steps for hypothesis testing and write the conclusions in APA style. Calculate and interpret the effect size for this test.

- Alternative Hypothesis (\(H_1\)): The mean cell phone usage of the professor's students is less than the general population's usage (60%). Show more…

The adoption of smart phones and social media apps has been much discussed. One aspect of these devices is that students tend to be distracted by their phones during class. A recent survey reported that 86% of 1004 randomly selected females used their smart phones during class time, compared to 81% of 1009 randomly selected males. Do these results confirm a higher smart phone usage among females? Use a significance level of α = 0.05. a. Give the name of the hypothesis test that would be appropriate for this situation. (1 point) b. State the hypotheses in symbols. (2 points) c. Use your calculator to perform the appropriate hypothesis test and report the test statistic and p-value. (3 points) d. Write a full conclusion for this test in the context of the problem. (2 points) e. Find a 90% confidence interval for the difference in the proportion of males and females who use their phone during class. (2 points) f. Interpret the confidence interval in the context of this problem. (2 points) g. Does this confidence interval support your conclusion in part (e)? Explain. (2 points)

A 2012 survey of 2,290 American adults indicates that 15% of cell phone owners do their browsing on their phone rather than a computer or other device. (a) According to an online article, a report from a mobile research company indicates that 35 percent of Chinese mobile web users only access the internet through their cell phones. Conduct a hypothesis test to determine if these data provide strong evidence that the proportion of Americans who only use their cell phones to access the internet is different than the Chinese proportion of 35%. Use a significance level of α=0.08. H0: prop = 0.35 HA: prop ≠ 0.35 p-value: Based on this information, we may: - Reject the Null Hypothesis - Accept the Null Hypothesis - Reject the Alternative Hypothesis - Accept the Alternative Hypothesis (b) Calculate a 97% confidence interval for the proportion of Americans who think the Civil War is still relevant.

Section 10.2 - Hypothesis Tests for a Population Proportion Cell Phones and Cancer In a study of 420,095 Danish cell phone users, 135 subjects developed cancer of the brain or nervous system (based on data from the Journal of the American Cancer Institute as reported in USA Today). Test the claim of a once popular belief that such cancers are affected by cell phone use. That is, test the claim that cell phone users develop cancer of the brain or nervous system at a rate that is different from the rate of 0.0340% for people who do not use cell phones. Because this issue has such great importance, use a 0.005 significance level. Based on this study should cell phone users be concerned about cancer of the brain or nervous system? Step 1 Ho: H1: Type of Tail: Step 2 α : Step 3 po = x = ̂p = n = z = (̂p - p0) / √(p0(1 - p0) / n) = Step 4 [Draw the region & find p-value using StatCrunch, Minitab, or a calculator] Step 5 (Compare the p-value to the α level and state whether we reject or fail to reject the null) Step 6 (Conclusion of the test):
