The One Sample 2 Test ESP A husband and wife claim that they have a special bond that allows them to communicate by ESP. To test this claim, an researcher puts the husband and wife in separate rooms. The husband is randomly shown one of colors: either blue, red, green, yellow or orange. He then is given 5 seconds to use his ESP to communicate the color to his wife. The wife then has to decide which of the 5...
The 5 summary statistics for the homework and final scores of 64 randomly selected students from a large Chemistry class of 2000 students are given in the table below. Avg SD Homework 76 15 Final 64 20 r= 0.15 a. Find the slope and y-intercept of the sample regression equation for predicting Finals from Homework.
