O Yes, this model is appropriate because the number of customers is concave down between t= 0 and t= 10.

Transcribed Image Text:A local coffee shop models the number of customers in its shop according to the time of day (t= 0 corresponds to the opening time of 5:00 a.m.) by counting customers at certain times and taking the average number of customers over a one-month period.
The coffee shop uses the polynomial regression N(f) = –0.07 – 0.04P + 5.2t + 30 with the coefficient of determination 2 = 0.94.
