Two samples from the same population both have M = 84 and s2 = 20; however, one sample has n = 10 and the other has n = 20 scores. Both samples are used to evaluate a hypothesis that μ = 80 and to compute Cohen’s d. How will the outcomes for the two samples compare?

Isee the amount was $90.00 then reduced to $75.00 , what is the percent ?

Aball is thrown from a height of 139 feet with an initial downward velocity of 15 ft/s. the ball's height h (in feet) after t seconds is given by the following. h=139-15t-16t^2 how long after the ball is thrown does it hit the ground? round your answer(s) to the nearest hundredth. (if there is more than one answer, use the "or" button.) t =

If you answer 2+2 you will get over 80 points
