An Industrial Psychologist Is Investigating the Effects of Work Environment

question 49

Multiple Choice

An industrial psychologist is investigating the effects of work environment on employee attitudes. A group of20 recently hired sales trainees were randomly assigned to one of four different ?home rooms? - five traineesper room. Each room is identical except for wall color. The four colors used were light green, light blue, grayand red. The psychologist wants to know whether room color has an effect on attitude, and, if so, wants tocompare the mean attitudes of the trainees assigned to the four room colors. At the end of the trainingprogram, the attitude of each trainee was measured on a 60-pt. scale (the lower the score, the poorer theattitude) . The data was subjected to a one-way analysis of variance. Give the null hypothesis for the ANOVA Ftest shown on the printout. ONE-WAY ANOVA FOR ATTITUDE BY COLOR
$\begin{array} { l | c | r | r | r | c } \text { SOURCE } & \text { DF } & { \text { SS } } & { \text { MS } } & { \mathrm { F } } & \mathrm { P } \\\hline \text { BETWEEN } & 3 & 1678.15 & 559.3833 & 59.03782 & 0.0000 \\\text { WITHIN } & 16 & 151.6 & 9.475 & & \\\text { TOTAL } & 19 & 1829.75 & & &\end{array}$

• A) \(\mathrm { H } _ { 0 } : \mu _ { \mathrm { g } }\) reen \(= \mu _ { \mathrm { blue } } = \mu _ { \mathrm { gray } } = \mu _ { \mathrm { red } }\), where the \(\mu _ { \text {'s represent mean attitudes for the four rooms } }\)
• B) \(\mathrm { H } _ { 0 } : \mu _ { 1 } = \mu _ { 2 } = \mu _ { 3 } = \mu _ { 4 } = \mu _ { 5 }\), where the \(\mu _ { \mathrm { i } }\) represent attitude means for the ith person in each room
• C) \(\mathrm { H } _ { 0 } : \mathrm { x } _ { 1 } = \mathrm { x } _ { 2 } = \mathrm { x } _ { 3 } = \mathrm { x } _ { 4 }\), where the \(\mathrm { x } ^ { \prime }\) s represent the room colors
• D) \(\mathrm { H } _ { 0 } :\) Pgreen \(=\) Pblue \(=\) Pgray \(=\) pred, where the p's represent the proportion with the corresponding attitude

Calculate and interpret z-scores for individual data points within a normal distribution.

Apply the empirical rule to estimate the percentage of data within specific ranges of a normal distribution.

Determine the percentage of data above, below, or between certain values in a normal distribution using standard normal distribution tables or calculations.

Apply knowledge of normal distributions to real-world examples involving human characteristics and behaviors.
