Question

6. Suppose an online television and movie streaming service has determined that viewers who watched the entire first season of one of its original series take an average of 5.9401 days, with a standard deviation of 3.9405 days. One of their analysts wants to determine at a significance level of 0.05 whether new customers who begin watching the series within a week of the start of their subscription finish watching the season more quickly. He selects a SRS of 1300 new customers who began watching the first season of the series during the first week of their subscription and calculates the mean amount of time to be 5.7797 days. Conduct the appropriate test of significance: (a) State the null hypothesis H0 and the alternative hypothesis Ha. (b) Calculate the test statistic. Round to 2 decimal places. (c) Find the P-value. Round to 4 decimal places. Include a diagram of the distribution with the area shaded. (d) Compare the P-value with the significance level ? (see question 3 exam- ples) and then write the conclusion (i.e., There is sufficient evidence / There is not sufficient evidence ...). Show your work.
