Answer:
4%/ a interest compounded semi-annually
Step-by-step explanation:
The option that gives the lower interest rate payment would be more appropriate. to determine this calculate the effective interest rate
Effective annual rate = (1 + APR / m ) ^m - 1
M = number of compounding
(1 + 0.04/2)^2 - 1 = 4.04%
(1 + 0.04/12)^12 - 1 = 4.07%
the choice should be 4%/ a interest compounded semi-annually
Answer:
Sales are expected to increase positively.
Step-by-step explanation:
The model is y =7-3*X1+5*X2
Here, y is the depended variable and X1 and X2 are independent variable.
Holding the unit price constant X2 (television advertisement) is increase by $1 dollar
SSR= 3500
SSE=1500
So, TSS = SSR+SSE = (3500+1500) = 5000
Now r^2= 1 - (SSR/TSS) = 1 - (3,500/5,000) = 1 - 0.70 = 0.30
So, the sample correlation coefficient (r) = (0.3)^(1/2) = 0.547
We can conclude that sample correlation indicates a strong positive relationship.
