ValentinkaMS [17]

Answer:

Given:

Null hypothesis: the average salary for new college graduates with a job is $50,556.

Alternative hypothesis: the graduates from a university earn more than that average.

Using the z-test:

t = (mean of sample - mean of null hypothesis)/(std/sqrt(number of sample)

 = (53200 - 50556)/(10200/sqrt(100))

 = 2.592 > 1.645

=> Reject the null hypothesis, their graduates earn more than average

Hope this helps!
