Answer 1

Answer #1

Since , the value of the population standard deviation is not known.

Therefore , use t-distribution.

Therefore , the correct output is (A)

The correct option is ,

A , Since we only have the sample standard deviation but not the population standard deviation

Question number 7 The ABC battery company claims that their batteries last 100 hours, on average. You decide to conduct a test to see if the company's claim is true. You believe that the mean life may be different from the 100 hours the company claims. You decide to collect data on the average battery life (in hours) of a random sample of n 20 batteries. Some of the information related to the hypothesis test is presented below. Test of...

The manufacturer of a certain brand of auto batteries claims that the mean life of these batteries is 45 months. A consumer protection agency that wants to check this claim took a random sample of 24 such batteries and found that the mean life for this sample is 43.35 months. The lives of all such batteries have a normal distribution with the population standard deviation of 4.5 months. Find the p-value for the test of hypothesis with the alternative hypothesis...

A popular flashlight that uses two D-size batteries was selected, and several of the same models were purchased to test the "continuous-use life" of D batteries. As fresh batteries were installed, each flashlight was turned on and the time noted. When the flashlight no longer produced light, the time was again noted. The resulting "life" data from Rayovac batteries had a mean of 20.6 hours. Assume these values have a normal distribution with a standard deviation of 1.3 hours. (Give...
