Step-by-step explanation:
We are given the following in the question:
We are conducting a one tailed hypothesis test with alternate hypothesis
The z test calculated for the same is
z=2.3
We calculate the p-value from the standard normal table.
p value = 0.010724 at 0.05 significance level.
The result is significant
p value = 0.010724 at 0.01 significance level.
The result is not significant
p value = 0.010724 at 0.02 significance level.
The result is significant at 0.02 significance level.

Option c. The result is significant at the 0.020.02 level.
