Question

in a statistics class, a teacher had the students complete an activity in which they grabbed as many bite - sized pretzels as they could with their dominant hand, without crushing them. the teacher then measured their handspan in centimeters. the computer output displays the regression analysis.
predictor coef se coef t - ratio p
constant - 14.71 4.317 1.609 0.046
handspan 1.585 0.310 5.114 0.000
s = 3.05 r - sq = 52.1% r - sq(adj) = 54.7%
which of the following represents the typical distance between the actual and predicted numbers of pretzels?
0.310
3.05
4.317
5.114

Explanation:

Step1: Recall the concept of standard error of the estimate

The standard error of the estimate ($s$) represents the typical distance between the actual and predicted values in a regression model.

Step2: Identify the value of $s$ from the given output

In the provided regression output, we can see that $s = 3.05$.

Answer:

3.05
