Question
A simple random sample of size
at the alphaαequals 0.10
level of significance?
nequals=40 is drawn from a population. The sample mean is found to be
106.5, and the sample standard deviation is found to be 17.8.
Is the population mean greater than 100at the alphaαequals 0.10
level of significance?
Determine the null and alternative hypotheses.
Upper H0:
mu equals 100μ
Upper H1:
mu greater than 100μ
Compute the test statistic.
t 0 equals2.31
Determine the P-value.
