Question 1 A man claims to be a psychic. In a carefully controlled test, an experimenter stared at a color, either red or black (the colors were chosen at random by a computer), for one minute. The purported psychic was able to correctly name the color seen by the experimenter 59 times in 100 trials. Should we be impressed by this?

Question 2 Fill in all of the question marks below with the correct values.

Pooled StDev =   0.9619              -1.0       0.0       1.0       2.0

Question 3 Fill in all of the question marks below with the correct values (the sample size is 24 so there are 22 df). What is the value of the sample correlation between the predictor and the response?

The regression equation is
response = ???? + ???? predictor

Predictor        Coef     SE Coef          T        P
Constant      -0.0138      0.1710      ?????    ????? 
predicto      -0.5681      0.1337      ?????    ?????

S = 0.8269      R-Sq = 45.1%     R-Sq(adj) = 42.6%
