Giving a test to a group of students, the grades and gender are summarized below
A | B | C | Total | |
Male | 17 | 3 | 16 | 36 |
Female | 18 | 6 | 19 | 43 |
Total | 35 | 9 | 35 | 79 |
Let ππ represent the percentage of all male students who would receive a grade of B on this test. Use a 90% confidence

- A student organization surveyed both current students and recent graduates to obtain information on the quality of teaching at a particular university. An analysis of the responses provided the following teaching-ability rankings. Professor O Ho: Ps+0 H₂: Ps=0 O Ho: Ps ≤0 Ha: P >0 1 Ho: Ps > 0 H₂: Ps=0 2 Ho: Ps= 0 Ha: Ps * 0 3 4 5 6 7 9 10 Current Students 4 6 8 3 1 2 5 10 7 9 Recent Graduates 6 8 5 1 2 3 7 Do the rankings given by the current students agree with the rankings given by the recent graduates? Compute the rank correlation between current students and recent graduates. (Round your answer to three decimal places.) 9 Use α = 0.10 and test for a significant rank correlation. State the null and alternative hypotheses. O Ho: P₂ ZO Ha: Ps <0 10 4 Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value. (Round your answer to four decimal places.) p-value= What is your conclusion? O Reject Ho. There is not sufficient evidence to conclude…arrow_forwardThe boxplot shown below results from the heights (cm) of males listed in a data set. What do the numbers in that boxplot tell us? 154 173.8 194 169.7 183.5 The minimum height is cm, the first quartile Q, is cm, the second quartile Q, (or the median) is cm, the third quartile Q, is cm, and the maximum height is cm.
