mew\" 17 An SRS of 110 ights of a large airline (call this airline 1) showed that 87 were on time. An SRS of 110 flights of another T-"es (Summing large airline (call this airline 2) showed that 98 were on time. Let p1 and p2 be the proportion of all flights that are on 1 time for these two respective airlines. ls airline 2 more reliable? In other words, does airline 'l have a lower on-time rate Marked out of compared to airline 2? Carry out an appropriate test using a significance level of 0.05. 9.00 \\p Flag (a) What are the null and alternative hypotheses? question H03 p1 7 p2 = 3 0.0 3 HA:p1p2 0.10 v A it) Based on the p-value, those conducting the test should reject v the null hypothesis at the significance level of 0.05. (Q) What is the appropriate conclusion? (9) What is the appropriate conclusion? 0 There is insufficient evidence to conclude there is a difference in males and females for car preference. 0 There is sufficient evidence to conclude there is no difference in males and females for car preference. 0 There is insufficient evidence to conclude the proportion of males is not the same for each car preference. 0 There is sufficient evidence to conclude there is a difference in males and females for car preference. 0 There is sufficient evidence to conclude the proportion of males is not the same for each car preference. Question 22 T-"es re-na'ning: 'l Marked out of 10.00 \\V Flag question Olivia attends school at the University of Alberta and decides to compile a contingency table of students who are taking various degrees. She surveys a group of students, and the data she collects is listed in the contingency table below. Olivia want to see if degree and gender are dependent variables. (a) In performing this statistical test, state the hypotheses. O Ho: The proportion of female students is the same as the proportion of male students vs. Ha: The proportion of female students is not the same as the proportion of male students 0 Ho: Degree and gender are dependent vs. Ha: Degree and gender are independent 0 Ho: Degree and gender are independent vs. Ha: Degree and gender are dependent O Ho: Degree is associated with gender vs. Ha: Degree is not associated with gender 0 Ho: Degree is related to gender vs. Ha: Degree is not related to gender (b) What is the expected frequencies of each cell? Fill out the table. (Round your answers to 2 decimal places, if needed) (c) What is the test statistic value for this hypothesis test? (Round your answers to 2 decimal places, if needed.) (d) The test statistic follows a chisquare distribution with df = 21? . (e) Using the statistical table, the pevalue is 0.025
