Help with following:Interpret the slopeInterpret the y-intercept.Predict the bone mineral density of the femoral neck of a woman who consumes two colas per week.The researchers found a woman who consumedtwo colas per week to have a bone mineral density of0.826 g/cm Is this woman's bone density above or below average among all women who consume two colas per week? Because colas tend to replace healthier beverages and colas contain caffeine and phosphoric acid, researchers wanted to know whether cola consumption isassociated with lower bone mineral density in women. The accompanying data lists the typical number of cans of cola consumed in a week and the femoral neckbone mineral density for a sample of 15 women.

The y-intercept is the value of y where the line crosses the y-axis. => The value of y when x is zero is 0.900 The bone mineral density of the femoral neck of a woman who consumes two colas per week is ŷ = -0.025*2 + 0.900 = 0.85 The researchers found a woman who consumed two colas per week to have a bone mineral density of 0.826 g/cm. This woman's bone density is below average among all women who consume two colas per week.

A group of researchers studied the effect of acid rain on wildlife and collected n = 12 samples from streams in different States. They recorded the pH (X) of the water (i.e. units above pH 7), and the BCI, a measure of biological diversity (Y). The data obtained is summarized below.
