Based on Floretta's study regarding how many new customers she gain per year, an the following results, conclude whether to reject or not reject H0.

H0: μ=163; Ha: μ>163
x¯=167
σ=11
α=0.01 (significance level)
The test statistic is
z0=x¯−μ0σn√=167−1631125√=1.82
The critical value is z0.01=2.33.

Select two responses below.

Select all that apply:

Do not reject H0. At the 1% significance level, the test results are not statistically significant and at best, provide weak evidence against the null hypothesis.
Reject H0. At the 1% significance level, the data provide sufficient evidence to conclude that the mean yearly new customers is more than 163 people.
The test statistics is NOT in the rejection region.
The test statistic is in the rejection region.
