- Question: A CEO wondered if her company … either more or less complaint from its worker on Monday than any other day. She … that if it were truly random 20% of the complaint should have been … on Monday. She randomly … 50 complaints and … that day that they were … in those complaints 13 were submitted on a Monday. The CEO conducts a one-proportion hypothesis test at the 5% significance level test whether the true proportion of complaints … on Monday is different from 20%. (a). Ho : p = 0.2; Ha : p #0.2 which is two tailed test. (b). Use excel to test whether the true proportion of complaints submitted on a Monday is different from 20%. Identify the test statistics, z, and p-value from the excel output, rounding to three decimal places.
- Question: A CEO wondered if her company … either more or less complaint from its worker on Monday than any other day. She figured that if it were truly random 20% of the complaint should have been filed on Monday. She randomly selected 50 complaints and … that day that they were submitted in those complaints 13 were submitted on a Monday. The CEO conducts a one-proportion hypothesis test at the 5% significance level, to test whether the true proportion of complaints … on Monday is different from 20%. (a). Ho : p = 0.2; Ha : p #0.2 which is two tailed test. (b). zo = 1.061, p-value is = 0.289 (C). Which of the following are appropriate conclusions for this hypothesis test? Select all that apply.
- Question: Dimitry … that his friend is using of weighted die for board games to test his theory he want to see whether the proportion of odd number is different from 50%. He … the die 40 times and got an odd number 14 times. Dimitry conducts a one proportion hypothesis test at the 5% significance level, to test whether the true proportion of odd is different from 50%. (a) Which answer Choice shows the correct null and alternative hypothesis for this test?
- Question: Dimitry suspects that his friend is using a … die for board games. To test his theory, he wants to see whether the proportion of odd number is different from 50%. He rolled the die 40 times and got an odd number 14 times. Dimitry conducts a one proportion hypothesis test at the 5% significance level, to test whether the true proportion of odd is different from 50%. (a) Ho : p = 0.5; Ha : p #0.5 which is two tailed test. (b) Use excel to test whether the true proportion of odds is different from 50%. Identify the test statistics, z, and p-value from the excel output, rounding to three decimal places.

- Question: Steve listens to his favorite streaming music service when he works out. He wonders whether the service’s algorithm does a good job of finding random songs that he will like more often than not. To test this, he listens to 50 songs chosen by the service at random and finds that he likes 32 of them. Use Excel to test whether Steve will like a randomly … song more often than not, and then draw a conclusion in the context of the problem. Use α=0.05.
