As due to the honor-code, we are authorized to answer only 3 subparts for each question and that you haven't specified which of the 3 subparts you want the solutions for, the first 3 subparts are being answered for now. Requesting you to re-upload the question stating the remaining subparts for the answers to them with all the required information. Let p1: proportion of the occupents not wearing a seat belt but got killed p2: proportion of the occupents wearing a seat belt but got killed∴p1=x1n1=382887 = 0.01316245237& p2 =x2n2= 107749 = 0.001290489095 where, n1: number of observations in the first sample n2: number of observations in the second sample x1: number of successes in the first sample x2: number of successes in the second sample The hypothesises of the test are given as: E . H0 : p1 = p2 vs H1 : p1 > p2The test statistic of the test is given as: z = p1- p2 p^ (1-p^ )(1n1+1n2) = 8.1233where, p^ = n1x1 + n2x2n1+n2= 0.004512974803 Therefore, the value of the test statistics z =8.1233The P-value of the test is obtained as: P(X >zo= 8.1233) = 0.0000001 Therefore, the P-value is 0.0000001

40 people are randomly sent to walk one of four trails. The time (in minutes) they spend completing each trail is recorded in the table below. (a) Test to see if the times needed to complete a trail vary. Use a 0.05 significance level. (b) Test each pair (A/B, A/C, A/D, B/C, B/D, C/D) to see which trails have a statistically significant difference. Indicate your p-value for each comparison, and when the effect is statistically significant (use 0.05 as your significance level), declare which trail of the two takes more time to complete. Trail A - 30, 33, 41, 27, 36, 31, 37, 40, 29, 35 Trail B - 27, 33, 38, 41, 40, 38, 35, 44, 41, 39 Trail C - 25, 34, 41, 39, 32, 30, 36, 35, 27, 33 Trail D - 41, 39, 46, 37, 40, 42, 50, 42, 50, 33, 47, 43
Suppose an instructor would like to know if there is difference in the performance of her two courses of 560 students each.

A shareholders' group is lodging a protest against your company. The shareholders group claimed that the mean tenure for a chief exective office (CEO) was at least 11 years. A survey of 62 companies reported in The Wall Street Journal found a sample mean tenure of 9.3 years for CEOS with a standard deviation of s = 4.4 years (The Wall Street Journal, January 2, 2007). You don't know the population standard deviation but can assume it is normally distributed. You want to formulate and test a hypothesis that can be used to challenge the validity of the claim made by the group, at a significance level of a = 0.05. Your hypotheses are: H.:µ > 11 На: :и < 11 What is the test statistic for this sample?
