The data describe promotional spending by a pharmaceutical company. The share is the market share of their product in a certain region. The detail voice is the ratio of promotional visits to doctor's offices for their product to the total number of visits forsimilar drugs. The sample voice is the share of samples in the market that are from this company. Formulate the multiple regression model with y given by the market share and x given by the detail voice and sample voice.

Prev The table below gives the list price and the number of bids received for five randomly selected items sold through online auctions. Using this data, consider the equation of the regression line, y = bo + b₁x, for predicting the number of bids an Item will receive based on the list price. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, In practice, It would not be appropriate to use the regression line to make a prediction if the correlation coefficient is not statistically significant.
