In a simple linear regression study the predictor is the monthlyadvertising expenditure (expressed in $10,000s), and the responseis the sales revenue (expressed in $100,000s). A regression programgave the following estimates for the intercept and the slope:β0 = -0.1 and Β1 = 0.7 You want aninterval estimate for next month's sales revenue, given that theadvertising expenditure will be x=2 (that is, $20,000). You areusing a statistical program to do find this interval. The programasks you whether you want a "confidence interval" or a "predictioninterval". Which of the two is appropriate here?
Question 20 options:
a. Confidence Interval
b. Prediction Interval
c. Both intervals are good
d. Neither interval are relevant in this situation
