$200 x 12 = 2,400 (number of pencils they bought in 2006)
3/4 x 2,400 = 1,800 (number of pencils they used)
2,400 - 1,800 = 600 (number of pencils remaining)
1,800 - 600 = 1,200 (number of pencils needed)
They had to buy 1,200 more pencils in 2007.
Answer:
Step-by-step explanation:
95% prediction interval for the dependent variable when the independent variable value is 20,
assuming the fitted regression line is: Y = 1.50 + 6.0(X).
Assume the sample size is 20
Y = 1.50 + 6.0(X)
sample X = 20
here predicted value = 1.5+6*20
= 121.5
therefore 95% prediction interval for the dependent variable
the standard error of the regression (SEE) is 1.2.
