Fill volumes of cans of air freshener are known to follow a normal distribution. You take a random sample of 5 cans and you calculate a sample mean of 400 ml. The sample standard deviation is calculated to be 6 ml. A 98% confidence interval for the true mean fill volume of all cans of air freshener is: 400 8.43 400 10.05 400 9.22 400 7.89 400 6.24 Fill volumes of cans of air freshener are known to follow a normal distribution.
