Annuity
a Large Annuity Company Holds Many Industry Group Stocks

question 34

Short Answer

Annuity
A large annuity company holds many industry group stocks.Among the industries are banks,business services and construction.Seven companies from each industry group are randomly sampled to test the hypothesis that the mean price per share is the same among industries.The data are: $$\begin{array} { | l | l | l | } \hline { \text { Banks } } & { \text { Business Services } } & { \text { Construction } } \\\hline n _ { 1 } = 7 & n _ { 2 } = 7 & n _ { 3 } = 7 \\\bar { x } _ { 1 } = 41 & \bar { x } _ { 2 } = 30 & \bar { x } _ { 3 } = 24 \\\sum _ { i = 1 } ^ { n _ { 1 } } \left( x _ { 1 } - \bar { x } _ { 1 } \right) ^ { 2 } = 882 & \sum _ { i = 1 } ^ { n _ { 2 } } \left( x _ { i 2 } - \bar { x } _ { 2 } \right) ^ { 2 } = 1266 & \sum _ { i = 1 } ^ { n _ { 1 } } \left( x _ { i 3 } - \bar { x } _ { 3 } \right) ^ { 2 } = 582 \\\hline\end{array}$$
-Compute the mean square error (MSE).

Definitions:

General Adaptation Syndrome

A three-stage model (alarm, resistance, exhaustion) that describes the physiological changes the body undergoes when under stress.

Resistance Stage

The second stage of the General Adaptation Syndrome, where the body adapts to and resists stress through continued hormone and energy production.

Alarm Stage

The initial reaction of the body to stress, activating the fight or flight response as part of the general adaptation syndrome.

Exhaustion Stage

The exhaustion stage is the final phase of the stress response, where the body's ability to resist stressors diminishes significantly after prolonged exposure, leading to depletion of energy and possible health deterioration.
