Question 2 20 points Save Answe A researcher at Central Hartford University is testing out a new super long-lasting chewing gum. He knows that, on average, the population chews a piece of regular gum for a mean of u = 16.2 minutes before spitting it out, but the standard deviation of the population is unknown. A sample of n=24 students is given the new long-lasting gum. Students in this sample chewed for mean of 20.0 minutes with standard deviation s = 3.1 minutes. Use an a = .05 to test whether the new gum is chewed longer than regular gum. Answer the following: a. State the null and alternative hypotheses b. What is the value of the test statistic? Show your work. c. The p value is less than 0.001. Draw your conclusions. Can you reject the null hypothesis? Does this long-lasting chewing gum actually work?
