Suppose we want to test the claim that all supermodels have heights that are greater than 172 cm, using a significance level of 1%. Find the corresponding that statistic and p-value. (your p-value can be reported as a range of possible results)
Added by Shelby S.
Step 1
This translates to a one-tailed hypothesis test where: - H0 (Null Hypothesis): The average height of supermodels is less than or equal to 172 cm. - H1 (Alternative Hypothesis): The average height of supermodels is greater than 172 cm. Show more…

Assume a significance level of ? = 0.05 and use the given information for the following: a. State a conclusion about the null hypothesis. (Reject H 0 or fail to reject H 0 . ) b. Without using technical terms, state a final conclusion that addresses the original claim. Original claim: Women have heights with a mean equal to 160.00 cm. The hypothesis test results in a Pvalue of 0.0614.
Hypothesis Testing
Basics of Hypothesis Testing
The heights are measured for a simple random sample of nine supermodels. They have a mean height of 70 inches and a standard deviation of S equals 1.5 inches. A data set of 40 randomly selected women who are not super models has a mean of 63.2 inches and a standard deviation of S equals 1.27 inches. Use a .01 significance level to test the claim that the mean height of supermodels is greater than the mean height of women who are not super models.
