As a part of her studies, Olivia gathered data on the durations of 28 wildfires in the western United States. She works through the testing procedure: H0:μ≥15; Ha:μ<15 α=0.04 The test statistic is t0=x¯−μ0sn√=−1.16. The critical value is −t0.04=−1.819. At the 4% significance level, does the data provide sufficient evidence to conclude that the mean duration of a wildfire in the western United States is less than 15 days? Select the correct answer below: We should reject the null hypothesis because t0<tα. So, at the 4% significance level, the data provide sufficient evidence to conclude that the average duration of a wildfire in the western United States is less than 15 days. We should not reject the null hypothesis because t0<tα. So, at the 4% significance level, the data do not provide sufficient evidence to conclude that the average duration of a wildfire in the western United States is less than 15 days. We should reject the null hypothesis because t0>tα. So, at the 4% significance level, the data provide sufficient evidence to conclude that the average duration of a wildfire in the western United States is less than 15 days. We should not reject the null hypothesis because t0>tα. So, at the 4% significance level, the data do not provide sufficient evidence to conclude that the average duration of a wildfire in the western United States is less than 15 days.

Question
As a part of her studies, Olivia gathered data on the durations of 28 wildfires in the western United States. She works through the testing procedure:
- H0:μ≥15; Ha:μ<15
- α=0.04
- The test statistic is t0=x¯−μ0sn√=−1.16.
- The critical value is −t0.04=−1.819.
Select the correct answer below:
We should reject the null hypothesis because t0<tα. So, at the 4% significance level, the data provide sufficient evidence to conclude that the average duration of a wildfire in the western United States is less than 15 days.
We should not reject the null hypothesis because t0<tα. So, at the 4% significance level, the data do not provide sufficient evidence to conclude that the average duration of a wildfire in the western United States is less than 15 days.
We should reject the null hypothesis because t0>tα. So, at the 4% significance level, the data provide sufficient evidence to conclude that the average duration of a wildfire in the western United States is less than 15 days.
We should not reject the null hypothesis because t0>tα. So, at the 4% significance level, the data do not provide sufficient evidence to conclude that the average duration of a wildfire in the western United States is less than 15 days.
