41. A vendor at the local farmer's market sells 5-lb bags of apples and 2.5-lb bags
of apples. Which equation best describes
the number of 5-lb bags, f, and 2.5-lb
bags, t, that the vendor can create with
30 pounds of apples?
A 7.50f + t) = 30
B 5f + 2.5t = 30
C 2.5(f + t) + 5 = 30
D 2.5f + 5t= 30

A. find the power of the test, when the null hypothesis assumes a population mean of mu = 450, with a population standard deviation of 156, the sample size is 5 and the true mean is 638.47 with confidence intervals of 95 b. find the power of the test, when the null hypothesis assumes a population mean of mu = 644, with a population standard deviation of 174, the sample size is 3 and the true mean is 744.04 with confidence intervals of 95% c. find the power of the test, when the null hypothesis assumes a population mean of mu = 510, with a population standard deviation of 126, the sample size is 10 and the true mean is 529.44 with confidence intervals of 95
