in a maze running study, a rat is run in a t maze and the result of each run recorded. a reward in the form of food is always placed at the right exit. if learning is taking place, the rat will choose the right exit more often than the left. if no learning is taking place, the rat should randomly choose either exit. suppose that the rat is given n = 100 runs in the maze and that he chooses the right exit x = 66times. would you conclude that learning is taking place? (use α = 0.01.)
state the null and alternative hypotheses.
h0: p = 0.5 versus ha: p ≠ 0.5h0: p < 0.5 versus ha: p > 0.5 h0: p = 0.5 versus ha: p > 0.5h0: p ≠ 0.66 versus ha: p = 0.66h0: p = 0.66 versus ha: p ≠ 0.66
find the test statistic and the p-value. (round your test statistic to two decimal places and your p-value to four decimal places.)
z = p-value =
state your conclusion.
the p-value is less than alpha, so h0 is rejected
there is insufficient evidence to indicate that learning is taking place. the p-value is greater than alpha, so h0 is not rejected.

Apinhole camera is made out of a light-tight box with a piece of film attached to one side and pinhole on the opposite side. the optimum diameter d(in millimeters) of the pinhole can be modeled by d=1.9[ (5.5 x 10^-4) l) ] ^1/2, where l is the length of the camera box (in millimeters). what is the optimum diameter for a pinhole camera if the camera box has a length of 10 centimeters
