A study of 18 worldwide financial institutions showed the correlation between their assets and pretax profit to be 0.79. Can we conclude that there is a positive correlation between assets and pretax profit?
1-b. State the decision rule for 0.10 significance level: H0: ρ ≤ 0; H1: ρ > 0. (Round your answer to 3 decimal places.)
Reject H0 if t >
Reject/ Don't Reject HO. It is reasonable/ unreasonable to conclude that there is a positive association in the population between assets and pretax profit

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;...
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 22 flights, the correlation between the number of passengers and total fuel cost was 0.640. 1. State the decision rule for 0.050 significance level: H0: ρ ≤ 0;...

The mean annual tuition and fees in the 2013-2014 academic year for a sample of 24 private colleges in California was $37,000 with a standard deviation of $7800. A dot plot shows that it is reasonable to assume that the population is approximately normal. Can you conclude that the mean tuition and fees for private institutions in California is greater than $35,000? Use the α=0.10 level of significance and P-value method with the Critical Values for the Student's t Distribution...
