Answer: A. (636.9, 653.1)
Step-by-step explanation:
Given : Sample size : n=56
Significance level :
Critical value :
Sample mean : 
Standard deviation : 
The 95% confidence interval for population mean is given by :-
Hence, 95% confidence interval for population mean is (636.9, 653.1).
The function that best represents the data is y = 0.75x + 4.5. The slope in this case represents the increase in the amount she spends in $ due to the number of cards she makes. The intercept with the Y axis (4.5) means that she has an expense of 4.5 $ without having made any card yet.
Original investment is V
In the first year V decreased by 0.08V to give V - 0.08V
In the second year; V - 0.08V increased by $450 to give V - 0.08V + $450
The value (n) after two years = V - 0.08V + $450
The correct choice is 'D.'
