Question 1042849
a) this is a one-tailed test since H1 does not contain = sign
:
b) At a 5% significance level, the critical value for a one tailed test is found from the table of z-scores to be 1.645
Reject when z > 1.645
:
c) standard error of the mean (SE) = population standard deviation / square root(sample size)
SE = 6 / square root(32) approx 1.061
z value = (32 - 29) / 1.061 approx 2.83
:
d) reject H0 since 2.83 > 1.645
:
e) a z-score of 2.83 has a p-value of 0.0026
