Question 286770: A stats practitioner wishes to test the following hypothesis H0:μ = 600 against H1:μ<600. A sample of 50 observations yielded the statistics: mean = 585 and standard deviation = 45. The test statistic of a test to determine there is enough evidence at the 10% signigicance level to reject the null hypothesis is?

A stats practitioner wishes to test the following hypothesis
H0:μ = 600 against
H1:μ<600.
A sample of 50 observations yielded the statistics: mean = 585 and standard deviation = 45. The test statistic of a test to determine there is enough evidence at the 10% signigicance level to reject the null hypothesis is?
------
t(585) = (585-600)/[45/sqrt(50)] = -2.3570
==========
