Question 141514: The management of White Industries is considering a new method of assembling its golf cart. The present method requires 42.3 minutes, on the average, to assemble a cart. The mean assembly time for a random sample of 24 carts, using the new method, was 40.6 minutes, and the standard deviation of the sample was 2.7 minutes. Using a 0.10 level of significance, setup a Hypothesis test. Can we conclude that the assembly time using the new method is faster?

The management of White Industries is considering a new method of assembling its golf cart.
----------------------
The present method requires 42.3 minutes, on the average, to assemble a cart.
----------------------
The mean assembly time for a random sample of 24 carts, using the new method,
was 40.6 minutes, and the standard deviation of the sample was 2.7 minutes.
----------------------
Using a 0.10 level of significance, setup a Hypothesis test.
----------------------
Can we conclude that the assembly time using the new method is faster?
----------------------------------------
What is the standard deviation for the present method?
If you know that you can run a 2-sample t test.
