A small business ships specialty homemade candies to anywhere in the world. Past records indicate that the weight of orders is normally distributed. Suppose a random sample of 16 orders is selected and each is weighed. The sample mean was found to be 110 grams with a standard deviation of 14 grams. a. What is the standard error? b. For 90% confidence level, what is the margin of error? c. Based on the sample results, what is the lower bound of the 90% confidence interval? d. Based on the sample results, what is the upper bound of the 90% confidence interval?
