Before connecting the encoder and decoder rats, the researchers wanted to verify that the decode rats were
Question:
(a) Compute a 95% Wilson-adjusted confidence interval for the accuracy rate for this rat and interpret the interval in the context of the question.
(b) Using your interval computed in part (a) to support your answer, are you convinced that this rat's accuracy rate is better than simple guessing (i.e., 50% accuracy)?
(c) Using your interval computed in part (a) to support your answer, are you convinced that this rat's accuracy rate is better than 70%?
(d) Use a χ2 goodness-of-fit test, to test whether or not the accuracy rate exceeds 70%. Use α = 0.05.
