Bob Nale is the owner of Nale's Texaco GasTown. Bob would like to estimate the mean number of litres (L) of gasolines Customers. Assume the number of litres sold follows the normal distribution with a standard deviation of 2 L. From his re selects a randam 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). 100 such intervals were determined, the population (Click to select) v would be included in about intervals.
