According to a Pew Research Center study, in May 2011, 34% of all Type numbers in American adults had a smart phone (one which the user can use to the boxes. read email and surf the Internet). A communications professor at a 10 points university believes this percentage is higher among community college students. She selects 339 community college students at random and finds that 136 of them have a smart phone. In testing the hypotheses: Ho: p = 0.34 versus Ha: p > 0.34, she calculates the test statistic as z = 2.3779. Then the p-value = (Please round your answer to four decimal places.) Question 10 According to a study on the effects of smoking by pregnant women Type numbers in on rates of asthma in their children, for expectant mothers who the boxes. smoke 20 cigarettes per day, 22.6% of their children developed Part 1: 10 asthma by the age of two in the US. A biology professor at a points university would like to test if the percentage is lower in another *by Part 2: 10 country. She randomly selects 336 women who only deliver one child points and smoke 20 cigarettes per day during pregnancy in that country and finds that 66 of the children developed asthma by the age of two. 20 points In this hypothesis test, the test statistic, z = and the p-value = (Round your answers to four decimal places.) Question 11 According to the Pew Research Center, the proportion of the Select one answer. American population who use only a cellular telephone (no landline) 10 points is 37%. Jason claims that the proportion of young American adults who do not have a landline is greater than 37%. He conducts a survey with a sample of randomly selected young American adults and finds that 38% do not have landlines. If we set up our null and alternative hypotheses as follows: Ho : p = 0.37 Ha : P > 0.37 and find that: "p-value"=0.418. Does this provide enough evidence to support Jason's claim? Use an a=0.05 level of significance. Choose the correct answer below. A. Since the p-value a, do not reject the null hypothesis. C. Since the p-value a, reject the null hypothesis
