The commercial director of a major daily newspaper in the Quebec region affirms that more than 76% of households in this region read at least one daily newspaper. A survey of 1,000 households in the Quebec region indicates that 800 households read at least one daily newspaper.

Is the sales manager's assertion supported by the results of the survey significance level = 0.10?

A) Since the calculated Z value = 2.962 > the critical Z value = 1.96, the results do not contradict the sales manager's assertion. The proportion seems to be over 76%.

B) Since the calculated Z value = 2.962 > the critical Z value = 2.58, the results are not in contradiction with the assertion of the commercial director. The proportion seems to be over 76%.

C) Since the calculated Z value = 2.962 > the critical Z value = 1.28, the results do not contradict the sales manager's assertion. The proportion seems to be over 76%.

D) Since the calculated Z value = 2.962 > the critical Z value = 2.33, the results do not contradict the sales manager's assertion. The proportion seems to be over 76%.

E) Since the calculated Z value - 2.962 > the critical value of Z= 1.645, the results are not in contradiction with the assertion of the commercial director. The proportion seems to be over 76%. Previous page Next part Page 10 of 10 10 deputy
