Using the calculator display inputs down below, make a decision
to reject or fail to reject the null hypothesis at a significance
level of   = 0.05.

SCREEN 2:

Z-TEST

POPULATION MEAN NOT EQUAL TO 60

Z = -2.31498774

P = 0.0206136

Sample mean = 57.75

n = 35

Choose the correct answer.

Since the P-value is greater than significance level (a), reject
the null hypothesis.

Since the P-value is less than significance level (a), fail to
reject the null hypothesis.

Since the P-value is greater than significance level (a), fail
to reject the null hypothesis.

Since the P-value is less than significance level (a), reject
the null hypothesis.
