Question
Transcribed Image Text:A report states that the mean yearly salary offer for students graduating with mathematics and statistics degrees is $62,935. Suppose that a random sample of
50 mathematics and statistics graduates at a large university who received job offers resulted in a mean offer of $63,400 and a standard deviation of $3,700. Do
the sample data provide strong support for the claim that the mean salary offer for mathematics and statistics graduates of this university is greater than the
national average of $62,935? Test the relevant hypotheses using a = 0.05.
USE SALT
Find the test statistic and P-value. (Use technology to calculate the P-value. Round your test statistic to two decimal places and your P-value to four decimal
places.)
t =
P-value =
State your conclusion.
O Reject Ho. We do not have convincing evidence that the mean salary offer for mathematics and statistics graduates of this university is greater than the
national average of $62,935.
O Reject Ho. We have convincing evidence that the mean salary offer for mathematics and statistics graduates of this university is greater than the national
