Question 1168566: It's well established that lab rats require, on average, 32 trials before reaching a criterion of 3 consecutive errorless trials in a complex water maze. To determine whether a mildly painful stimulus has any effect on performance, a sample of twelve rats were given a mild electrical shock just before each trial. They required the following number of trials before reaching the criterion: 35, 37, 38, 34, 32, 31, 35, 29, 30, 35, 35, 39. Does the mild shock affect the rats performance?
Questions are: 1. Statistical Hypotheses?
2. Reject the null hypothesis at the .05 level of significance if t ≥ __ or or t ≤ __ given __ df.
3. Given that the mean of the sample is 34.17 with a sample standard deviation of 3.13, calculate the one sample t test by hand.
4. What is your decision?
5. How do you interpret your decision?
