Suppose the number of beds filled per day in a mediumsized hospital is normally distributed. A hospital administrator tells the board of directors that, on the average, at least 184 beds are filled on any given day. One of the board members believes that the average is less than 184 and she sets out to test to determine if she is correct. She secures a random sample of 16 days of data (shown below). Use α = 0.05 and the sample data to test the board member’s theory. Assume the number of filled beds per day is normally distributed in the population.

Number of Beds Occupied per Day
173 149 166 180
189 169 152 194
177 169 188 160
199 175 172 187



(Round the intermediate values to 2 decimal places. Round your answer to 2 decimal places.)

The value of the test statistic is and we

reject the null hypothesis or

A sociologist studied gender differences in the average number of hours worked per day among employees at a law firm (there are 42 men and 19 women employed at this firm). She obtained the following results: men work, on average, 52 hour per week and women work, on average, 56 hour per week. The standard deviation for men is 12 hours and the standard deviation for women is 9 hours. Test the null hypothesis of no difference in the average...
