John wishes to study the heights of the women’s basketball team. He completes a simple random sample of women’s basketball team members. The results are listed below:
70 71 69.25 68.5 69 70 71 70 70 69.5 74 75.5
John knows that women’s heights are normally distributed. Use the critical value method and a 5% significance level to test the claim that women’s basketball players have heights with a mean greater than 68.6 inches (population mean height of men).
What population parameter is being tested?
Group of answer choices
Standard Deviation or Variance
Goodness-of-Fit or Independence or Homogeneity
Proportion
Linear Correlation Coefficient
Mean
Solution:
Claim to be tested is " that women’s basketball players have heights with a mean greater than 68.6 inches "
i.e. , here we are testing the claim about the mean (population mean)
So , answer is
Mean

8. Listed below are the heights (inches) for the simple random sample of supermodels. Use a 0.05 significance level to test the claim that supermodels have heights with a mean that is greater than the mean height of 63.8 in. for women in the general population. Do not use the p-value. 70 71 69.25 68.5 69 70 71 70 70 69.5
The data table contains frequency distribution of the heights of the players in a basketball league. a. Calculate the mean and standard deviation of this population. b. What is the probability that a sample mean of 40 players will be less than 69.5 in.? c. What is the probability that a sample mean of 40 players will be more than 71 in.? d. What is the probability that a sample mean of 40 players will be between 70 and 71.5...
