Question

< Question 11 of 17 > Attempt 5 Assume a media agency reports that it takes television streaming service subscribers in the United States an average of 6.03 days to watch the entire first season of a television series, with a standard deviation of 3.98 days. Suppose Elizabeth, an analyst for an online television and movie streaming service company, wants to determine if her company's customers exhibit similar viewing rates for their series offerings. She formulated the null hypothesis Ho:# = 6.03 days and the alternative H:#76.03 days, where is the mean number of days that it takes for customers to watch the first season of a series. She conducted a one-sample z-test based on data collected from a simple random sample of 820 customers who watched the first season of a television series from the company database of over 20,000 customers that qualified. She assumed that that the population standard deviation is o = 3.98 days. She compiled the summary statistics shown in the table, Sample Sample Standard size error mean x 6.33 SE 820 0.14 Compute the P-value for Elizabeth's hypothesis test directly using a normaledf function on a Ti calculator or software. You may find some software manuals helpful. Provide your answer with precision to four decimal places. Avoid rounding until the final step P-value = 0.0309 Incorrect

Answer 1

The value of the test statistcis is

I 11 o/vn

6.33-6.03 014 2.143

The P-value is = 0.0321
