Economics Question Help ▼ A market researcher collects a simple random sample of customers from a population of over a million customers that use a home improvement website After analyzing the sample, she states that she has 95% confidence that the mean time customers spent on that website per day is between 20 and 55 minutes. Suppose that the population mean time customers spent on that website is 49 minutes a day. Does this value of the population mean help to show that the confidence interval estimate is correct? Explain. Choose the correct answer below lar O A. Yes, because the population mean, u, is included within the confidence interval estimate. O B. No, because the population mean, p, is not in the middle half of the confidence interval estimate O C. Yes, because the population mean, u is within 95% of the midpoint of the confidence interval estimate O D. No, because the population mean, u is not the midpoint of the confidence interval estimate. O E. No, because the population mean, u is not included vwithin the confidence interval estimate. or S iedi unc Srrect: 1 e To ihle

Current Attempt in Progress How Many Birds Do Domestic Cats Kill? "Domestic cats kill many more wild birds in the United States than scientists thought," states a recent article.1 Researchers useda sample of n = 140 households in the US with cats to estimate that 35 % of household cats in the US hunt outdoors. A separate study? used KittyCams to record all activity of n = 55 domestic cats that hunt outdoors. The video footage showed that the mean number of kills per week for these cats was 2.4 with a standard deviation of 1.51. Find a 90 % confidence interval for the mean number of kills per week by US household cats that hunt outdoors. Round your answers to three decimal places. The 90 confidence interval is

Facebook Friends Many people believe that the average number of Facebook friends is 140. The population standard deviation is 39.6. A random sample of 30 high school students in a particular county revealed that the average number of Facebook friends was 147. At a=0.10, is there sufficient evidence to conclude that the mean number of friends is greater than 140? Use the P-value method. Use a graphing calculator. Part 1 of 4 (a) State the hypotheses and identify the claim. Ho: 140 not claim H₁>140 claim This hypothesis test is a one-tailed Part: 1/4 Part 2 of 4 test. (b) Find the P-value. Round the answer to at least four decimal places. P-value=
