An experiment is conducted to show that blood pressure can be consciously reduced in people trained in a "biofeedback exercise program." six (6) subjects were randomly selected and the blood pressure measurements were recorded before and after the training. the difference between blood pressures was calculated
(after ? before)
producing the following results:
xd = ? 10.2, sd = 8.4.
using the data, test the hypothesis that the blood pressure has decreased after the training.

what is the distribution for the test?

If jm equals 5x -8 and lm equals 2x -6 which expression represents jl

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:
