Facebook: A study showed that two years ago, the mean time spent per visit to Facebook was 20.8 minutes. Assume the standard deviation is a=8.0 minutes. Suppose that a simple random sample of 107 visits was selected this year and has a sample mean ofx18.8 minutes. A social scientist is interestec to know whether the mean time of Facebook visits has decreased. Use the a =0.10 level of significance and the critical value method with the table. (a) State the appropriate null and alternate hypotheses. (b) Compute the value of the test statistic. (c) State a conclusion. Use the u =0.10 level of significance.

I need help with stats/2023, section 7.2 and 7.3, please help with TI-84 commands A car company says that the mean gas mileage for its luxury sedan is at least 22 miles per gallon (mpg). You believe the claim is incorrect and find that a random sample of 5 cars has a mean gas mileage of 21 mpg and a standard deviation of 5mpg. At α=0.10, test the company's claim. Assume the population is normally distributed. Which sampling distribution should be used and why? A. Use a normal sampling distribution because the population is normal, and σ is known. B. Use a normal sampling distribution because the population is normal, and σ is unknown. C. Use a t-sampling distribution because the population is normal, and σ is unknown. D. Use a t-sampling distribution because n<30. E. Use a t-sampling distribution because the population is normal, and σ is known F. Use a normal sampling distribution because n>30.
