2. The table below shows the results of an experiment that relates the height at which a ball is dropped, x, to the height of its first bounce, y. Drop Height (x)
(cm) Bounce Height (y)
(cm)
100 26
90 23
80 21
70 18
60 16

Find , the mean of the drop heights. Find , the mean of the bounce heights. Find the linear regression equation that best fits the data. Write the equation you would use to show that is a point on the line of regression.

Suppose a gym membership has an initial enrollment fee of $75 and then a fee of $29 a month. which equation models the cost, c, of the gym membership for m months?

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
