A detection device is used to monitor the level of carbon monoxide (CO) in the air.The following data, in ppm (parts per million) were collected from a single location inside a recreation facility:

7.288.505.568.184.036.989.137.345.568.699.057.98

Question:Engineers at the American Society of Heating, Refrigeration and Air Conditioning want to know whether the average maximum indoor carbon monoxide (CO) level in this facility is less than 9ppm.At 1% do the sample data support this claim?

Perform a hypothesis test using the 5-step process:

a)State Ho and H1 in symbols and in words in the context of the problem.Identify which hypothesis is the claim and determine the type of test (right-tail, left-tail, two tail).

b)Determine the critical value and label it --for example, z = 1.96or t = -2.421, etc).

c)Compute the test value.If you are using the p-value method, then include the p-value of the test.

d)Make the decision toReject HoorDo not reject Ho.

e)State your complete conclusion in the context of the claim.
