You are given the following information obtained from a random
sample of 5 observations. Assume the population has a normal
distribution. 420 520 501 472 615 You want to determine whether or
not the mean of the population from which this sample was taken is
significantly greater than 420 at 90% confidence level.
a.State the null hypotheses. (In symbolic)
b.State the alternative hypotheses. (In symbolic)
c.Value of the standard error of the mean.
d.Test statistics value
e.Critical value
f.What is the conclusion?
