Question 1072036: A recent survey of 8,000 high school students found that the mean price of a prom dress was $195.00 with a standard deviation of $12.00. Alyssa thinks that her school is more fashion conscious and that students spent more than $195.00. She collected data from 20 people in her high school and found that the average price spent on a prom dress was $208.00. Which of the following are the correct null hypothesis and alternate hypothesis?
H0: u=195; Ha: u >195
H0: u ≠ 195; Ha: u=208
H0: u=195; Ha: u≠195
H0: u=195 ; Ha: u≥208

The best hypothesis is Ho: mu is less than or equal to 195
Ha: mu is greater than 195.
This isn't one of the choices, but the first is closest to it.
