Which of the following is false?
Correlation measures the strength of linear association between two numerical variables.
If the correlation between two variables is close to 0.01, then there is a very weak linear relation between them.
Correlation coefficient and the slope always have the same sign (positive or negative).
if the correlation coefficient is 1, then the slope must be 1 as well.
A simple random sample of size 19 is obtained from a population that is normally distributed with a mean of 43,8 and a standard deviation of 2. Is the sampling distribution normally distributed? Why?
Yes, the sampling distribution is normally distributed because the population is normally distributed
No, the sampling distribution is not normally distributed because the population is not normally distributed
Yes, the sampling distribution is normally distributed because the population mean is greater than 30
No, the sampling distribution is not normally distributed because the sample size is less than 30.
1. The false statement is:
If the correlation coefficient is 1, then the slope must be 1 as well.
2. Yes, the sampling distribution is normally distributed because the population is normally distributed.
