A Television Studio Did a Poll to Determine Whether Women

question 37

Essay

A television studio did a poll to determine whether women in different age groups watched different amounts of comedy programming. Check the TI-84 output to see whether the same-variance condition for ANOVA holds. Show your work. Is ANOVA appropriate?
$$\begin{array} { | l l l l l | } \hline \text { One-way ANOVA } & & & & \\ \mathrm { F } = 1.739515653 & \text { Cat } & \mathrm { n } & \text { Mean } & \text { StDev } \\ \mathrm { p } = .2092138468 & 17 - 24 & 25 & 3.42 & 1.28 \\ \text { Factor } & 25 - 32 & 15 & 4.50 & 3.45 \\ \mathrm { df } = 2 & 33 - 40 & 21 & 2.17 & 0.75 \\ \mathrm { SS } = 16.3611111 & & & & \\ \mathrm { MS } = 8.18055556 & & & \\ \text { Error } & & & \\ \mathrm { df } = 15 & & & \\ \mathrm { SS } = 70.5416667 & & & \\ \mathrm { MS } = 4.70277778 & & & \\ \mathrm { Sxp } = 2.16858889 & & & \\ \hline \end{array}$$

Definitions:

Half-Wave Rectification

A process that converts alternating current (AC) to direct current (DC) by allowing only one half of the AC cycle to pass through.

AC Circuit

Pertains to an electrical circuit in which the current changes direction periodically, as opposed to a DC (Direct Current) circuit where current flows in one direction only.

Reverse Bias

A condition in semiconductor devices where the voltage is applied in the opposite direction of the forward bias, often to block current flow.

Initial Cost

The initial expenditure involved in starting a project, acquiring an asset, or initiating an investment.
