Question 2 Suppose it is reported that 74 % of people subscribe to a cable or satellite television service. You decide to test this claim by randomly sampling 135 people and asking them if they subscribe to cable or satellite televsion. (Round your answer to 4 decimals when necessary) Is the distribution of the sample proportion normal? O Yes, the distribution of sample proportions is normal since np(1 − p) ≥ 10 O No, the distribution of sample proportions is not normal since np(1 − p) < 10 Hp = < What is the mean of the distribution of the sample proportion? > σp = What is standar deviation of the distribution of the sample proportion? = Suppose we find from our sample that 76 subscribe to cable or satellite television service. What is the sample proportion? What is the probability that at least 76 subscribe to cable or satellite television service?
