Answer:

Step-by-step explanation:

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

H_0 : x bar = 195\\H_a: x bar >195

(Right tailed hypothesis test)
