1.Consider the summary of a survey conducted by a marketing firm regarding environmental protection policies among residents of two regions of the country.

Region	Policy Good for Business & Jobs	Policy Threat for Business & Jobs
Region1	190	125
Region2	158	140

2.A random sample of 145 clients from a firm with 1450 clients, 132 indicated very high satisfaction with the firm's service. Estimate the upper end point in a 98% confidence interval for the proportion of all clients who are very highly satisfied with this firm.

3.Scores on COMM 215 final exams follow a normal distribution. If you are a randomly selected student for this exam, what is the probability that you will achieve a score that exceeds the average score by more than 1.25 standard deviations?

Find the p-value for testing the hypothesis that for Region1, "Good for Business & Jobs" is the dominant opinion on environmental protection policies by taking more than half of the support of responders of the survey.
