Answer:
1*(9+7):(2+6)*1=2
Step-by-step explanation:
Answer:
There is a significant linear correlation between the two variables.
Step-by-step explanation:
Given that part time weekly earnings are
x y
10 93
15 171
20 204
20 156
35 261
Correlation 0.9199
H0: r=correlatin =0
Ha: r ≠0
(two tailed test)
r difference = 0.9199
t = 
p value < 0.0001
Since p <0.05 we reject null hypothesis
There is a significant linear correlation between the two variables.
y-2= m(x-2)
Step-by-step explanation:
Y-y1=m(x-x1)
it's just plugging in the points to point slope formal
