0.67y + 4...when y = 2
0.67(2) + 4 = 5.34
0.67y + 4...when y = -2
0.67(-2) + 4 = 2.66
Answer:
75 miles
Step-by-step explanation:
Answer with explanation:
Given : The computed r -value = 0.45
Sample size : n=18
Degree of freedom :
Now, the critical value for Pearson correlation coefficient for a two-tailed test at a .05 level of significance will be :
( by critical correlation coefficient table)
Since , i.e. 0.45>0.468 , then we say that his Pearson correlation coefficient is not significant for a two-tailed test at a .05 level of significance.
