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?
Given that 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.
Since she wants to check whether sample mean x bar is the same as population mean mu = 195
