The number of different types of drinks that a barista makes in one week is related to the cost of the drink. a collection of data on the cost of a particular drink and the number of that drink made over the course of the week is shown in the table below, where x represents the cost of the drink, in dollars, and y represents the number of drinks made at each cost.
x y
1.85 97
2.10 84
2.45 66
3.25 70
3.50 65
3.65 58
4.15 51
4.45 40
4.70 44
5.10 27
using a residual plot, determine if the following model is a good fit for the data.
a.
yes. the model is a good fit because the residual plot does not have a random pattern.
b.
no. the model is not a good fit because the residual plot has a random pattern.
c.
no. the model is not a good fit because the residual plot does not have a random pattern.
d.
