2B. Enter and analyze the data below using JASP. It is from a sensory deprivation study looking at hearing threshold before or after one hour in a sensory deprivation chamber.Seven subjects participated in both before and after conditions in the actual study.Test the hypothesis that hearing should be more sensitive (thus lower numbers) after sensory deprivation compared with before.

BEFORE: 11, 34, 18, 33, 35, 22, 35AFTER: 13, 31, 18, 29, 32, 20, 28

Proper type of t-test to use: _____________________________________________

Is the hypothesis one-tailed or two-tailed? _____________________________________________

What is the significance level two-tailed?__________ What is the significance level one-tailed? __________

What is your conclusion based on this hypothesis test? Report in APA format.

2C. Use the same data as above but pretend that there were 14 subjects who were randomly assigned to two groups.One group was tested before deprivation, the other group after deprivation.Test whether or not the two groups in this design differ in their auditory sensitivity. (You will have to rethink the way you entered the data in order to do the analysis this way.)
