Question

Based on the regression output, which of the following is the predicted time, in minutes, that it took to gather the items if the order has 22 items?

Answer 1

Answer:

The predicted time, in minutes, that it took to gather the items if the order has 22 items is 63.8905 minutes

Step-by-step explanation:

Regression Output :

Predictor                            Coefficient

Constant                             3.0979

Square root of items          2.7633

R.sq.- 96.7%

So, with this data the regression equation is,

$\hat{y}=3.0979+2.7633x$

Now we are supposed to find the predicted time, in minutes, that it took to gather the items if the order has 22 items

Substitute x =22 in equation

$\hat{y}=3.0979+2.7633(22)$

$\hat{y}=63.8905$

Hence the predicted time, in minutes, that it took to gather the items if the order has 22 items is 63.8905 minutes
