A polling organization is checking its database to see if the data sources it used sampled the same ZIP codes. The variable Datasource Equals 1 if the data source is MetroMedia, 2 if the data source is DataQwest, and 3 if it's Rolling Poll. The organization finds that the correlation between five-digit ZIP code and DATAsource is minus0.0229. It concludes that the correlation is low enough to state that there is no dependency between ZIP code and Source of Data. Comment.

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
