Textbook Question

Chapter 12.6, Problem 41E

In Exercises 39-45, the correlation coefficient, r, is given for a sample of n data points. Use the α = 0.05 column in Table 12.19 on page 828 to determine whether or not we may conclude that a correlation does exist in the population. (Using the α = 0.05 column, there w a probability of 0.05 that the variables are not really correlated in the population and our results could be attributed to chance. Ignore this possibility when concluding whether or not there is a correlation in the population.)

n = 12 , r = 0.5
