A survey of 30 museums asked to provide the performance measure used most often for internal evaluation. A summary of Performance Measure Number of Museums the results is provided in the table. The data were analyzed using a chi-square test for a multinomial experiment. The results Total visitors are shown in the accompanying table. Complete parts a and b.

Test using a = 0.1. Choose the null and alternative hypotheses for testing whether one performance measure is used more often than any of the other types. O A.

Find a 90% confidence interval for the proportion of museums worldwide that use total visitors as their performance measure. Interpret the result. (Round to three decimal places as needed.) Interpret the result. Choose the correct answer below. A. A randomly selected museum will respond that total visitors is their performance measure 90% of the time. O B. A proportion of museums between the confidence limits will respond that total visitors is their performance measure. O C. There is 90% confidence that the true proportion of museums that use total visitors as their performance measure is contained in the confidence interval
