Confidence interval for the population mean problem

A random sample of 144 observations has a mean of 20, a median of 21, and a mode of 22. The population standard deviation is known to equal 4.8. The 95.44% confidence interval for the population mean is:

a. 15.2 to 24.8

b. 19.200 to 20.800

c. 19.216 to 20.784

d. 21.2 to 22.8
