Question
The Graduate Management Admission Test
(GMAT) is a test required for admission into many
masters of business administration (MBA)
programs. Total scores on the GMAT are normally
distributed. The Graduate Management Admission
Council, who administers the test, claims that the
mean total score is 528. Suppose a random sample
of 11 students took the test, and their scores are
.given below
490 ,450 ,413,727,663,521 ,550,414,560,699
500
Does the sample evidence suggest the mean total
?score is different from at the level of significance
The test statistic value, is
(s = 109.6559 Consider)
with 11 degrees of freedom to = 0.4922
with 10 degrees of freedom to = 0.4922
z0 = 1.6324
z0 = 0.4922
