Question 4 (1 point)

Suppose it is known that the mean and standard deviation of the scores on a statistics final are 74.45 and 5.75, respectively. Calculate an interval that is symmetric around the mean such that it contains approximately 95% of scores. Assume that the scores have a normal distribution.

Question 4 options:

Access the hourly wage data on the below Excel Data File (Hourly Wage). An economist wants to test if the average hourly wage is less than $28. Assume that the population standard deviation is $8.

b-1. Find the value of the test statistic. (Negative value should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.)

Data on 72 randomly selected flights departing from the three major NYC airports

(a) Calculate the 90% confidence interval estimate of the average departure delay times for flights that departed from the NYC airports in 2013. Remember to define the variable of interest and state the distribution. Show all working.

(b) Assume that we want to be more confident that the true average is contained in the interval. Hence, we increase the confidence level to 95%. Without any calculation, explain what would happen to the confidence interval width and estimation precision if the confidence level is increased while all other factors remain the same.
