Answer:
(22.74,24.06) is the required 95% confidence interval for the population mean ACT score of University of Oklahoma students.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 121
Sample mean = 23.4
Sample standard deviation = 3.65
Level of significance = 0.05
Degree of freedom
95% Confidence interval:
Calculation of critical value:
Putting the values, we get,
(22.74,24.06) is the required 95% confidence interval for the population mean ACT score of University of Oklahoma students.
Break 48 into 40 and 8. 3(40) + 3(8). 3 times 40 is 120 and 3 times 8 is 24. So, 120+ 24= 144
