Question

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. Which of the following statements is true?

A small business ships specialty homemade candies to anywhere in the world. Past records indicate that the weight of orders is nomally 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. Which of the following statements is true? O A The standard error is 14 grams. O B. The sampling distribution for the sample mean follows the t-distribution with 16 degrees of freedom. Show Timer O C. The sampling distribution for the sample mean is Normal with a mean of 110 grams and standard deviation of 14 grams. YQuestion Completion Status: D. The sampling distribution for the sample mean follows the t-distribution with 15 degrees of freedom.

Explanation / Answer

ans= random sample (n)=16

degree of freedom =n-1

=16-1=15

ans=D

The sampling distribution for the sample mean follows the t-distribution with 15 degrees of freedom.
