Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. A coin mint has a specification that a particular coin has a mean weight of 2.5g. A sample of 36 coins was collected. Those coins have a mean weight of 2.49473g and a standard deviation of 0.01818g. Use a 0.05 significance level to test the claim that this sample is from a population with a mean weight equal to 2.5g. Do the coins appear to conform to the specifications of the coin mint?
What are the hypotheses?
A. Upper H 0: mu equals 2.5g Upper H 1: mu less than2.5g
B. Upper H 0: mu not equals2.5 g Upper H 1: mu equals 2.5g
C. Upper H 0: mu equals2.5 g Upper H 1: mu greater than or equals2.5g
D. Upper H 0: mu equals2.5 g Upper H 1:mu not equals2.5g
Solution
