In recent yeаrs, there hаs been increаsing cоncern abоut health effects оf computer terminals. It is know that the miscarriage rate under general conditions is about 15%. A random sample of 700 pregnant women working with a computer 1 to 20 hours per week was taken. For this sample, there were 125 miscarriages. a) We wish to test the hypothesis that “short-term exposure (e.g., 1 to 20 hours per week) to computer terminals increases the rate of miscarriages”. State the appropriate hypotheses. b) Using a significance level of 0.05, test the hypotheses in part (a). [Make sure to check the requirements to provide the appropriate test statistic, p-value or critical value, decision, and conclusion.]
