A manager uses the SLR model to study the relationship between price (X) and weekly demand (Y) of a certain product. She finds evidence of a linear relationship and wants an interval estimate for the mean weekly demand when the price is set at $25. We know: n = 5, X-bar = 20, sx² = 12.9, MSE = 12.3, and Y-hat = 100 - 3x Use 3.2 as the critical value and find the margin of error (m.o.e.) for the interval. (Show 1 decimal place.)
