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 1.689 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?
3.05
5.114
4.317
0.310

Explanation:

En un análisis de regresión, el valor de \(s\) (denominado error estándar de la estimación) representa la distancia típica entre los valores observados (números reales de pretzels) y los valores predichos por el modelo de regresión. En la salida del computador, se indica que \(s = 3.05\).

Answer:

3.05
