Question

89 randomly selected students who responded to a survey lived, on average, 12.9 miles away from Cañada College with a standard deviation of 13.7 miles.

1) Use the statistics provided to test the claim that the average distance that student live from campus is larger than 10 miles. Use α = .05 to test this claim

the hypothesis test must contain:

1) Claim in terms of the appropriate parameter (e.g. μ = 4.5 m i l e s)

2) Null and alternative hypothesis

3) Sample evidence used

4) Test stat (z or t) , p-value and direction of test. (right, left or two tailed)

5) Whether you rejected or failed to reject the null hypothesis.

6) Conclusion telling us what the test concluded about your original claim.

2) If α = .01would you come to the same conclusion about the sufficiency of the evidence. Using the notion of Type 1 error, explain why your conclusion may have changed even though the evidence is the same.
