The sample is actually 55. what is the critical value? 5. To examine the effects of pets and friends in stressful situations, researchersrecruited 45 people to participate in an experiment. Fifteen of the subjects wererandomly assigned to each of three groups to perform a stressful task alone (controlgroup), with a good friend present, or with their dog present. Each subjects meanheart rate during the task was recorded. Higher heart rates mean more stress.

Suppose a government department would like to investigate the relationship between the cost of heating a home during the month of February in the Northeast and the home's square footage. The accompanying data set shows a random sample of 10 homes. Construct a 90% prediction interval to estimate the cost in February to heat a Northeast home that is 3,100 square feet.
