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.
