Interpret Confidence Interval 2

STATS-E1NTGD

You have calculated a confidence interval for the estimate of the slope to be $-2$ and $2$ with a level of significance of $.05$, what is your conclusion?

A

You estimate with $5\%$ confidence that the population slope is between $-2$ and $2$. Because this range includes $0$, you conclude there is not a significant linear relationship

B

You estimate with $95\%$ confidence that the population slope is between $-2$ and $2$. Because this range includes $0$, you would conclude there is not a significant linear relationship

C

You estimate with $5\%$ confidence that the population slope is between $-2$ and $2$. Because this range includes $0$, you conclude there is a significant linear relationship

D

You estimate with $95\%$ confidence that the population slope is between $-2$ and $2$. Because this range includes $0$, you would conclude there is a significant linear relationship
