Answer:
There is significant learning
Step-by-step explanation:
This is a test on comparison of a single proportion with a hypothesized proportion.
The subject of interest is whether rats really learn.
(Right tailed test)
n =100
Sample proportion p = 0.62
Std error of p assuming H0 to be true is
=
p difference = 0.12
Z statistic = p difference/std error =
p value = 0.0082
Since p <0.01, our alpha we reject null hypothesis
There is significant learning
