A test of hypothesis has the following details...

A test of hypothesis has the following details: H0: m = 8000. Ha: m > 8000, n = 50. s = 409. a = 0.01. x = 8158 Calculate the p-value and state the CORRECT decision for this test. P -value = 0.0032, fail to reject H0 p-value = 0.3863, fail to reject H0 p - value = 0.3483, reject H0 p-value = 0.0032, reject H0

Solution

test statistic = ( 8158 - 8000 ) / ( 409 / sqrt ( 50) )....
=  2.731611 .

p-value = 0.0032.....which is less than a=0.01..So, reject H0!
so, D) p-value = 0.0032 , reject H0............
