Q&H Company advertises during soap operas and football games. Each soap opera ad costs $75,000, and each football game ad costs $130,000. If S soap opera ads are purchased, they will be seen by 4S^1/2 million men and 22S^1/2 million women. If F football ads are purchased, they will be seen by 28F^1/2 million men and 10F^1/2 million women. The company wants at least 60 million men and at least 50 million women to see its ads.
Determine how to minimize Q&H’s cost of reaching the required number of viewers.

- Stock market analysts are continually looking for reliable predictors of stock prices. Consider the problem of modeling the price per share of electric utility stocks (Y). Two variables thought to influence this stock price are return on average equity (X1) and annual dividend rate (X2). The stock price, returns on equity, and dividend rates on a randomly selected day for 16 electric utility stocks are provided in the file P13_15.xlsx. Estimate a multiple regression equation using the given data. Interpret each of the estimated regression coefficients. Also, interpret the standard error of estimate and the R-square value for these data.arrow_forwardWhat is the implication of a data distribution with mean, median and mode being approximately equal?
