a. Explanation Calculation: In the given sample of 16 respondents, 4 preferred a faster pace of life, 11 preferred a slower place of life, and 1 said it did not matter. The level of significance is 0.05. The hypotheses are given below: Null hypothesis: H 0 : p = 0.50 . That is, there is no significant difference between the preferences for faster and slower paces of life. Alternative hypothesis: H 1 : p ≠ 0.50 . That is, there is a significant difference in the preferences for faster and slower paces of life. From the data set, it can be observed that the number of plus sign is 4 and the number of minus sign is 11. Therefore, the total number of respondents is 15. The sampling distribution for the number of plus signs is binomial with n = 15 and p = 0 .5 . Procedure: Step-by-step procedure to obtain the probability using Table 5 of Appendix B.is given below: Locate the value 15.0 in the left column of n. Find the row corresponding to all the values of x and column corresponding to the value 0.50 in Table 5 of Appendix B. From Table 5 in Appendix B, the binomial probabilities corresponding to n = 9 and p =0 .5 are tabulated below: x Probability 0 0.0000 1 0.0005 2 0.0032 3 0.0139 4 0 b.
