For a binomial distribution is found that male size X-1 is 0.4116 4. proportion of success - 03 and the probability when Referring to Problem H, what is the probability of at most one! 20.4116 b. 0.2401 C. 0.6517 Referring to Problem H, the variance is a 0.84 b, 0.92 c. always equal to the population mes d. 20. If two events are mutually exclusive, what is the probability that both occur at the same time? bos c. 1.00 d. Cannot be determined PROBLEMI After instituting some improvements, a bank wished to test whether customer service times at the drive-through window improved. The existing average service time was 110 seconds. A sample of 25 customers resulted in a mean of 100 seconds with a simple standard deviation of 40 seconds 21. Referring to Problem I, which hypotheses should they test? a. Z test of a population mean b. Zatest of a population proportion C. Mest of population mean d Mest of population proportion 22 Referring to Problem I the alternative hypothesis (H) states that the average service time is equal to 110 seconds b. the average service time is greater than 110 seconds c. the average service time is less than 110 seconds d the average service time is not equal to 110 seconds 23. Referring to Problem lifa -0.025 and test statistie -1.25. you would conclude that a. The null hypothesis is not rejected. b. The alternative hypothesis is not rejected. c. The null hypothesis is rejected. d. Insufficient information exists on which to make a decision Referring to Problem I how could this hypothesis test be incorrect? A sample of less than 30 customers was taken A t-test of hypothesis was done rather than a 2-test of hypothesis. Customers were chosen on the basis of the window they chose. Referring to Problem I how many degrees of freedom were used! a 2.158 25. Referring to Pr b. 0.10 d. 20 4 of 9
