![Bob Nale is the owner of Nale's Texaco GasTown. Bob would like to estimate the mean number of litres (L) of gasoline
Customers. Assume the number of litres sold follows the normal distribution with a standard deviation of 2 L. From his re
selects a random sample of 10 sales and finds the mean number of litres sold is 32.
a. What is the point estimate of the population mean? (Round the final answer to the nearest whole number.)
The point estimate of the population mean is
32 litres.
b. Develop a 95% confidence interval for the population mean. (Round the final answers to 3 decimal places.)
The 95% confidence interval for the population mean is between
30.761 and 33.239
c Interpret the meaning of part (b).
