A Sample of Recently Trained Line Workers Was Selected to Determine

question 24

Multiple Choice

A sample of recently trained line workers was selected to determine if there is a relationship between the number of hours of training time received by production line Workers and the time it took (in minutes) for them to trouble shoot their last process Problem were captured. Using the regression output is shown below, what conclusion Should be made at α = .05? The regression equation is Trouble Shooting $= 30.7 - 1.84$ Training
$\begin{array} { l r r r r } \text { Predictor } & \text { Coef } & \text { SE Coef } & T & \mathrm {~P} \\ \text { Constant } & 30.729 & 1.023 & 30.03 & 0.000 \\ \text { Training } & - 1.8360 & 0.1376 & - 13.35 & 0.000 \end{array}$
$$\mathrm { S } = 1.43588 \quad \mathrm { R } - \mathrm { Sq } = 93.2 \% \quad \mathrm { R } - \mathrm { Sq } ( \mathrm { adj } ) = 92.7 \%$$

• A) reject the null hypothesis, there is a significant relationship between amount of
• Training received and troubleshooting time
• B) do not reject the null hypothesis, , there is a significant relationship between
• Amount of training received and troubleshooting time
• C) reject the null hypothesis, there is no significant relationship between amount of
• Training received and troubleshooting time
• D) do not reject the null hypothesis, there is no significant relationship between
• Amount of training received and troubleshooting time
• E) None of these.
