One of the best-selling products.for a specialty grocery store is a 16-ounce package of almonds. Because it is impossible to pack exactly 16 ounces in each packet, a researcher has determined that the weight of almonds in each packet is normally distributed with a mean and a standard deviation equal to 16.01 ounces and 0.08 ounce, respectively a. Is the sampling distribution of the sample mean approximately normal based on any given sample size? Yes O No b. Find the probability that a random sample of 26 bags of almonds will average less than 16 ounces. Note: Round final answer to 4 decimal places. Probability 0.1841
