Answer:
No solution is possible from the provided information
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.
Answer:
0.45
Step-by-step explanation:
9/20 is the same as 0.45
The answer would have to be 30%
Divide the total cost by the amount of months
