Question

Using historical data, a ski resort has created a regression formula for forecasting daily demand (i.e. number of customers) based on the inches of snow on the ground and whether or not it's a Saturday or Sunday: 65 25(number of inches of snow on the ground) 40(1 if it's a Saturday/Sunday, 0 if it's a weekday). This formula means that weekends are always busier than weekdays regardless of the amount of snow on the ground. True False

Answer 1

True

Step-by-step explanation:

using the formula given

65 + 25(number of inches of snow on the ground) + 40(1 if it's a Saturday/Sunday, 0 if it's a weekday)

From the formula

let us assume it is a Saturday ( weekend ) and also assume 2 inches of snow

= 65 + 25 ( 2 ) + 40 ( 1 ) = 65 + 50 + 40 = 155 customers

lets assume a week day and also assume 2 inches of snow

= 65 + 25(2 ) + 40 (0 ) = 65 + 50 = 115 customers

from the calculations above we can conclude that the formula means that weekends are always busier than weekdays
