According to a recent survey, 16% of an adult population suffer from an anxiety disorder. Suppose a test of 300 random college students showed that 46 suffered from an anxiety disorder. Complete parts (a) and (b) below. . . . . . a. How many out of 300 would you expect to have an anxiety disorder if the 16% is correct? 48 adults (Type a whole number.) b. Suppose you are testing the hypothesis that the population proportion of college students suffering from an anxiety disorder is not 0.16 at the 0.05 significance level. Choose the correct figure below. O A. O B. Cc. Z= - 0.315 P = 0.6236 Z= - 0.315 P = 0.3764 Z= +0.315 p = 0.7528 Interpret the p-value. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or decimal rounded to two decimal places as needed.) O A. If 16% of the population suffer from an anxiety disorder, then there is a % chance we will observe a z-score of - 0.315 or greater. O B. If 16% of the population suffer from an anxiety disorder, then there is a % chance we will observe a z-score of - 0.315 or less. O C. There is a % chance that more than 46 out of 300 people will suffer from an anxiety disorder. O D. If 16% of the population suffer from an anxiety disorder, then there is a % chance we will observe a z-score less than - 0.315 or greater than 0.315
