The following data was drawn from an industry, there were 12 machine's working hours and number of units they could produce was tabulated as follows,

Hours (X)	80	79	83	84	78	60	82	85	79	84	80	62
Production(Y)	300	302	315	330	300	250	300	340	315	330	310	240

a) The management wish to know that the relation between working hours and their corresponding output is in a benefited way. Justify you answer with the management's hypothesis. Apply correlation coefficient formula for testing the hyposthesis.

b) Using appropriate software, you are asked to summarise the above statistical data you have been investigating in a method that can be understood by non-technical colleagues.

Data were collected on number of credit hours earned from a random sample of 40 JMU students. The mean was 57.2 and the standard deviation was 8.9. Conduct a test to determine whether the true mean number of credit hours earned differs from 55.0, allowing a Type I error rate of 0.05. Assume that the distribution of the number of credit hours earned is normal. Show your full work. You may not use your calculator’s built-in function.
