Solution:
From the given information, the output hypothesis test result for the population mean is shown.
Step 2
1. State the hypotheses.
Null hypothesis:
Alternative hypothesis:
Step 3
2. From the given output, the T-stat value is 0.804933.
Thus, the test statistic is 0.804933.
Step 4
3. From the given output, the P-value is 0.2106.
Thus, the P-value is 0.2106.
Step 5
4. Rejection rule:
If the P-value is less than or equal to 0.05, then reject the null hypothesis.
Conclusion:
Here, the P-value is 0.2106.
This is greater than 0.05.
By the rejection rule, do not reject the null hypothesis.
Thus, the mean tornado length is not greater than 2.9 miles.

A statistic is an unbiased estimator of a parameter when (a) the statistic is calculated from a random sample. (b) in a single sample, the value of the statistic is equal to the value of the parameter. (c) in many samples, the values of the statistic are very close to the value of the parameter. (d) in many samples, the values of the statistic are centered at the value of the parameter. (e) in many samples, the distribution of the statistic has a shape that is approximately NormalConstruct all random samples consisting three observations from the given data. Arrange the observations in ascending order without replacement and repetition.
