Answer:
Th computed value of the test statistic is 3.597
Step-by-step explanation:
The null and the alternative hypothesis is as follows:
Null Hypothesis:
the population correlation coefficient is equal to zero
the population correlation coefficient is not equal to zero
The test statistics for Pearson correlation coefficient is thus computed as :

where;
r = correlation coefficient = 0.60
n = sample size = 25
So;



t = 3.597
Comparing to a critical value of t (23 degrees of freedom two-tailed value) = 2.069
Decision Rule:
Since computed value of t is greater than the critical value of t; We reject the null hypothesis and accept the alternative hypothesis.
Conclusion:
We conclude that the population correlation coefficient significantly differs from 0 at 5% (0.05) level of significance.
Parallel would be anything with the slope of 4x and perpendicular would be anything with the slope of 1/4
Answer:
Number of Weeks - { 1, $120} {4, $480} {8, $960}
Step-by-step explanation:
First divide $1,800 by 15, which gives you 120. for for every week you add on $120. $120 times 4 gives us $480. 960 divided by 120 gives you 8 weeks. (i hope this helps :) )
