Use a graphing calculator to find an equation of the line of best fit for the data in the table. Round the slope and y-intercept to the nearest tenth. Then Identify and interpret the correlation coefficient. X 1.2, 2.6, 3.8, 4.1, 4.5, 5.2, 7.3, 8.6
Y 12.1, 14.6, 16.9, 19.3, 22.1, 24.5, 27.3, 30.1
The equation of the line of best fit is y=
To the nearest thousandth, the correlation coefficient is r=

Part a: select all of the ordered pairs that are located on the graph of the equation. part b: does the graph of the equation represent a function? select all correct answers for part a and one answer for part b.

According to a study conducted in 2015, 18% of shoppers said that they prefer to buy generic instead of name-brand products. suppose that in a recent sample of 1500 shoppers, 315 stated that they prefer to buy generic instead of name-brand products. at a 5% significance level, can you conclude that the proportion of all shoppers who currently prefer to buy generic instead of name-brand products is higher than .18? use both the p-value and the critical-value approaches.
