Please record your answer to 4 decimal places. 09824 What is the critical value that you would compare your sample correlation coefficient value t in order to test Ho: ρ:0 vs H, p-o using a 5% significance level? Please record your answer to 4 decimal places. What is your conclusion? Reject the null hypothesis and conclude that ρ is significantly different from zero oReject the alternative hypothesis and conclude that p is not significantly different from zero (cannot reject the null hypothesis and conclude that ρ is not significantly different from zero Cannot reject the alternative hypothesis and conclude that p is significantly different from zero This question is worth 3 marks.

    The Airline Passenger Association studied the relationship between the number of passengers on a particular flight and the cost of the flight. It seems logical that more passengers on the flight will result in more weight and more luggage, which in turn will result in higher fuel costs. For a sample of 25 flights, the correlation between the number of passengers and total fuel cost was 0.672. (1) State the decision rule for 0.05 significance level: H0: ρ ≤ 0;...
