Hypothesis testing of sprinklers

Reference no: EM13108288

Sprinkler Systems. A manufacturer of sprinkler systems designed for fire protection claims that the average activating temperature is at least 135 degrees F. To test this claim, you randomly select a sample of 32 systems and find the mean activation temperature between 133 degrees F with a standard deviation of 3.3 degrees F. At a level of significance of 0.10, do you have enough evidence to reject the manufacturers claim?

You need to do the following:

• Post the statement of this problem.

• Discuss the importance of obtaining a random sample.

• Identify the claim and state Ho and Ha.

• State the level of significance.

• Discuss the possibility of a Type I or Type II error.

On a separate page you need to do the following:

• Copy and paste the statement of the problem and your Ho and Ha from the previous page.

• Find the test statistic.

• Find the p-value.

• Decide whether to reject the null hypothesis.

• Interpret the decision in the context of the original claim.
