An independent-measures research study was used to compare two treatment conditions with n = 12 participants in each treatment. The first treatment had a mean of M = 55 with a variance of s2= 8
A man on the top of a building throws a ball at 18m/s at a 35 degree angle off a 165m building. Determine how fast the ball is moving if it strikes the ground.
In this exercise we relate the large sample confidence interval for Bernoulli parameter p to the hypothesis test: H0: p=p0 vs. Ha: p not equal to p0. Show that a (1-alpha)*100% confidence interval for p is precisely that set of all hypothesized p0
