Please help cant figure out

When a production process is operating correcy, the number of units produced per hour has a normal distribution with a mean of 104 and a standard deviation of 8. A random sample of 16 hours was taken. Complete parts {a} through [d]. a. Find the mean of the sampling distribution of the sample means. E (i) = :| (Type an integer or a decimal.) The fuel consumption, in miles per gallon, of all cars of a particular model has a mean of 2B and a standard deviation of 2. The population distribution can be assumed to be normal. A random sample of these cars is taken. Complete parts a and b below. a Click on the icon to View the standard normal table. a. Find the probability that the sample mean fuel consumption will be fewer than 2? miles per gallon it samples of 1, 4, and 9 are taken. The probability for a sample of 1 observation is El. (Round to four decimal places as needed}
