- Assume a media agency reports that it takes television streaming service subscribers in the U.S. an average of 6.14 days to watch the entire first season of a television series, with a standard deviation of 4.03 days. Scarlett is an analyst for an online television and movie streaming service company that targets to the 18-50 age bracket. She wants to determine if her company's customers exhibit shorter viewing rates for their series offerings. Scarlett plans to conduct a one-sample z-test, with significance level of a = 0.05, to test the null hypothesis, Ho: µ = 6.14 days, against the alternative hypothesis, H1: µ < 6.14 days. The variable u is the mean amount of time, in days, that it takes for customers to watch the first season of a television series. Scarlett selects a simple random sample of 825 customers who watched the first season of a television series from the company database of over 25,000 customers that qualified. She compiles the summary statistics shown in the table.…baby buster - Google Search .edu/webapps/assessment/take/launch.jsp?course_assessment_id=_804647_18&course_id%3_172595 1&content_id%3_15517779... ☆ Question Completion Status: QUESTION 6 A bakery makes brownies in batches of 72 and there is a 3.3% rate of defects.
