Mark performed a two-sample z-test for proportions to test the hypothesis that there was no difference in the proportion who support increasing student fees between male and female students at a particular university. Mark obtained a z-statistic of 0. Based on this information, which of the following is always true. The sample proportions will be the same for both male and female students at this university. O The sample proportions for both male and female students at this university will be 0. O All male and female students in the sample will feel the same way about supporting the increase in student foes. O The sample proportions for male and females will be the same as the hypothesized proportions for male and female students at this university.Use the following information to answer the next four problems: Test whether p1 > p2. The sample data are 21 = 116, n1 = 258, x2 = 135, ny = 311. Conduct a test at the a = 0.10 level of significance. Question 2 2 pts Determine the correct null and alternative hypothesis below. O Ho : p1 = 0 versus H1 : p1 # 0 O Ho : p1 = pa versus Hi : p1 # p2 O Ho : p1 = pa versus Hi : p1 > pz O Ho : p1 = pa versus H1 : PI P2- O Do not reject the null hypothesis because there is not sufficient evidence to conclude that PI # Pa.Use the following information to answer the next four problems: In an experiment, 1919 babies were asked to watch a climber attempt to ascend a hill. On two occasions, the baby witnesses the climber fail to make the climb. Then, the baby witnesses either a helper toy push the climber up the hill, or a hinderer toy preventing the climber from making the ascent. The toys were shown to each baby in a random fashion. A second part of this experiment showed the climber approach the helper toy, which is not a surprising action, and then the climber approached the hinderer toy, which is a surprising action. The amount of time the baby watched the event was recorded. The mean difference in time spent watching the climber approach the hinderer toy versus watching the climber approach the helper toy was 105 seconds with a standard deviation of 195 seconds.Question 6 2 pts State the null and alternative hypotheses to determine if babies tend to look at the hinderer toy longer than the helper toy. Let /'d = /hinderer - #helper, where /hinderer is the population mean time babies spend watching the climber approach the hinderer toy and /helper is the population mean time babies spend watching the climber approach the helper toy. OH, : Ad = 0 versus H1 : A 0 O H. : Ad # 0 versus Hi : Ha = 0 O Ho : /d = 0 versus Hi : pa # 0 Question 7 2 pts Assuming the differences are normally distributed with no outliers, test if the difference in the amount of time the baby will watch the hinderer toy versus the helper toy is greater than 0 at the 0.10 level of significance. Find the test statistic for this particular hypothesis test. 2.25 O 3.11 O 3.26 0 2.35Find the P-value for this hypothesis test. 0 0.015 0 0.099 O 0.144 0 0.519 Question 9 2 pts State the conclusion for this hypothesis test. O Reject Ho. There is sufficient evidence at the o = 0.10 level of significance to conclude that the difference is greater than 0. O Do not reject Ho. There is sufficient evidence at the or = 0.10 level of significance to conclude that the difference is greater than 0. O Reject Io. There is not sufficient evidence at the or = 0.10 level of significance to conclude that the difference is greater than 0. O Do not reject Ho. There is not sufficient evidence at the o = 0.10 level of significance to conclude that the difference is greater than 0.Question 10 2 pts Do people walk faster in an airport when they are departing (getting on a plane) or after they have arrived (getting off a plane)? An interested passenger watched a random sample of people departing and a random sample of people arriving and measured the walking speed (in foot per minute) of each. Which of the following tests is the most appropriate to use to determine if the mean walking speed is different between departing and arriving passengers at an airport (assuming all conditions for inference are satisfied)? O one-sample t-testO chi-square test Goodness Of Fit O two-sample z-test for proportions two-sample t-test O paired t-test Use the following set of data for the next four problems, assume that both populations are normally distributed. Population 1 Population 2 n 19 19 15.2 11.9 4.1 3.7 Question 11 2 pts Test whether # # #2 at the a = 0.01 significance level for the sample data. Determine the null and the alternative hypothesis for this test. O Ho : /1 = 2 versus $1 : /1 > #2 O Ho : my un versus H1 : / > / O Ho : #1 = pa versus H1 : 1 / Ha O Ho : # # pa versus H1 : #1 = #1Question 12 1.75 pts Determine the P-value for this hypothesis test. O 0.013 O 0.978 O 0.321 O 0.027 Question 13 2 pts Should the null hypothesis be rejected? O Do not reject Ho, there is not sufficient evidence to conclude that the two populations have different means. O Reject Ho, there is sufficient evidence to conclude that the two populations have different means. O Reject Ho, there is not sufficient evidence to conclude that the two populations have different means. O Do not reject Ho, there is sufficient evidence to conclude that the two populations have different means
