Answer:
The test statistic needed to evaluate the claim is t = -1.08.
Step-by-step explanation:
The test statistic is:

In which X is the sample mean,
is the expected value of the mean, s is the standard deviation of the sample and n is the size of the sample.
At a certain university, the average attendance at basketball games has been 3125. The athletic director claims that the attendance is the same as last year.
This means that 
Due to the dismal showing of the team this year, the attendance for the first 9 games has averaged only 2915 with a standard deviation of 585.
This means that 
What is the test statistic needed to evaluate the claim?



The test statistic needed to evaluate the claim is t = -1.08.
The answer is 58, because 2/5 is equal to 0.4, and 0.4 multiplied by 145 is 58.
15^2 + 20^2
= 225 + 400
= 625
square root of 625 = 25

(6+2*3)/(9-7)^2
(6+6)/(2)^2
12/4
3
Final answer: 3
Remember to simplify within parentheses first and then divide the two values in the end.
