Number of years after 2000 (x) 2 4 5 1 3 7 6
Percentage of people owning homes (y) 24% 32% 36% 20% 28% 44% 40%
What is the correlation coefficient for the data, and what does it represent?
0; it represents no correlation between x and y
1; it represents a perfectly linear positive correlation between x and y
1; it represents a perfectly linear negative correlation between x and y
−1; it represents a perfectly linear negative correlation between x and y

Determine if the following statement is true or false. the normal curve is symmetric about its​ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about its​ mean, because the mean is the balancing point of the graph of the distribution. the median is the point where​ 50% of the area under the distribution is to the left and​ 50% to the right.​ therefore, the normal curve could only be symmetric about its​ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with one​ peak, which means the​ mean, median, and mode are all equal.​ therefore, the normal curve is symmetric about the​ mean, mu. c. the statement is false. the mean is the balancing point for the graph of a​ distribution, and​ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of a​ distribution, and​ therefore, all distributions are symmetric about the mean.
