Answer:
18 is the sum of 17 and 1
Step-by-step explanation:
17+1=18
Yes, the confidence interval provides evidence that the average has changed. The prior year’s population mean expenditure per household, $632, is not within the 95% confidence interval, (635, 663).
100 % minus 18 % is 82% or .82
So multiply the price by .82 to get the sale price
300(.82)= 246
