Question
Because colas tend to replace healthier and colas contain caffeine and phosphoric acid, researchers wanted to know whether consumption of cola is associated with lower mineral density in women data shown in the accompanying table represent the typical number of cans of soda consumed in a week and the bone mineral density of the femoral neck for a sample of 15 women The data were collected through a prospective cohortstudy Complete parts (a) through (f EA Click the icon to view the data table Click the icon to view a table of critical values for the correlation coemcient (a) Find the least-squares regression line troating cola consumption per week as the explanatory variable choose the correctanswer below A The least squares regression ine is 00030x 0.8865. O B. The least-squares regression line is 08865x 00030 O C. The least-squares regression ine is y 08865x 00030 O D. The least-squares tegression ine is ya00030x 08885 Click to select your answers)Explanation / Answer
a)
Hence the equation of the line is A option
b)decrease, 0.0030
c)option A is the correct choice
d)dverage bone material density for 4 colas = 0.874614
e)So answer is below average
