A refrigeration unit at a restaurant is supposed to be kept at 40 times degree F An inspector would like to test the hypotheses ratio of cap h sub 0 to mu is equal to 40 versus ratio of cap h sub A to mu is not equal to 40 where μ= the true mean temperature for all times of the day. A 98 percent confidence interval based upon a random sample of 40 temperatures is 40 point 5 degrees to 42 point 1 degrees. Using the interval, what decision should be made?
Answer
A
The null hypothesis should be rejected at the alpha is equal to 0 point 0 2 level.
B
The null hypothesis should be rejected at the alpha is equal to 0 point 0 1 level.
C
The null hypothesis should not be rejected at the alpha is equal to 0 point 1 0 level.
D
The null hypothesis should not be rejected at the alpha is equal to 0 point 0 5 level.
