Astudy of 20 worldwide financial institutions showed the correlation between their assets and pretax profit to be 0.81.state the decision rule for 0.025 significance level: h0: rho ≤ 0; h1: rho > 0. (round your answer to 3 decimal places.)compute the value of the test statistic. (round your answer to 2 decimal places.)can we conclude that the correlation in the population is greater than zero? use the 0.025 significance level.

the number of buses
i am not completely sure on this one. it is indeed talking about vans and not buses, but there is no variable that would be for vans "v". so i'm going to go with, "the number of buses" because it says, there was only 64 seats, and 6 students didn't get a seat. so they had to ride a different van/bus. so 64 + 6 = 70. that means there is 1 filled bus with 64 students, and then another one that has 6 students. so there is 2 buses.
the length for each is 0.83
