1. The survey of the 25 graduates has a mean annual salary of $248,657 and a standard deviation of $103,027. At 5% level of significance, we want to test that the graduates from this school earn a mean annual salary of more than $200,000. What is your conclusion?

   		Reject H0, there is enough evidence to conclude that the mean salary is greater than $200,000
   		Reject H0, there is not enough evidence to conclude that the mean salary is greater than $200,000
   		Do not reject H0, there is enough evidence to conclude that the mean salary is greater than $200,000
   		Do not reject H0, there is not enough evidence to conclude that the mean salary is greater than $200,000
