An ABC new report stated that the mean distance that commuters in the United States travel each way to work is 16 miles. Assume the standard deviation is 8 miles. A sample of 75 commuters is chosen. What is the probability that the sample mean commute distance is greater than 13 miles? а. Choose the calculator function that would best apply to this problem (circle or highlight). i) Normalcdf ii) invNorm b. Which described scenario best applies to this problem (circle or highlight). i) Regular normal distribution problem ii) Normal distribution using the Central Limit Theorem for Means iii) Normal distribution using the Central Limit Theorem for Proportions c. Write down the entire calculator function that would input into your calculator to solve the problem. (DO NOT COMPUTE)
