Question 2. [3+4=7 Marks) Historical data indicates that the population standard deviation of the process is 7.6. Recent samples of size 20 produce a standard deviation of 70. a) Construct 95% confidence interval for the true population standard deviation. b) frest to determine if the variance has changed using a significance level of 0.05. nited States)

A consumer advocate claims that 70 percent of cable television subscribers are not satisfied with their cable service. In an attempt to justify this claim, a randomly selected sample of cable subscribers will be polled on this issue. (a) Suppose that the advocate's claim is true, and suppose that a random sample of 4 cable subscribers is selected. Assuming independence, use an appropriate formula to compute the probability that 3 or more subscribers in the sample are not satisfied with...

Historical data show that customers who download music from a popular Web service spend approximately $24 per month, with a standard deviation of $3. Assume the spending follows the normal probability distribution. Find the probability that a customer will spend at least $21 per month. How much (or more) do the top 7% of customers spend? What is the probability that a customer will spend at least 521 per month? (Round to four decimal places as needed.) How much do...
