To estimate weight of a certain product, 100 of these products are measured. The average weight and standard deviation are calculated to be 40 lb and 1 lb, respectively. 10,000 products are produced every day and assume normal distribution. We have to reject any product that weighs less than 38 lb. About how many products are rejected every day?
(How many products are expected to weight between 39 lb and 42 lb?
What is the 90% confidence interval on the mean weight?
