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. 0. Alyssa thinks that her school is more fashion conscious and that students spent more than $195. 0. She collected data from 20 people in her high school and found that the average price spent on a prom dress was $208. 0. Which of the following are the correct null hypothesis and alternate hypothesis? H0: Mu = 195; Ha: Mu greater-than 195 H0: Mu not-equals 195; Ha: Mu = 208 H0: Mu = 195; Ha: Mu not-equals 195 H0: Mu = 195; Ha: Mu greater-than-or-equal-to 208.
