The median number of part-time employees at fast-food restaurants in a particular city was known to be 16 last year. City officials think the use of part-time employees may be increasing. A sample of eleven fast-food restaurants showed that nine restaurants were employing more than 16 part-time employees, one restaurant was employing exactly 16 part-time employees, and one restaurant was employing fewer than 16 part-time employees. Can it be concluded that the median number of part-time employees has increased? Test using
?? = 0.05.
State the null and alternative hypotheses.
H0: Median > 16
Ha: Median = 16H0: Median = 16
Ha: Median < 16 H0: Median = 16
Ha: Median > 16H0: Median = 16
Ha: Median ? 16H0: Median ? 16
Ha: Median = 16
