A student in an AP Statistics class decided to conduct a study to determine whether you could predict the number of followers a teen has on Instagram based on the number of people he or she is following. To do this, she randomly selected fifty students from her high school that had Instagram accounts and for each student recorded the number of people they were following and the number of followers they had. A scatterplot of the data is shown.
The regression line is
.
followers=-45.3+1.21(following)
-We want to test: H₀: β = 0, H_a: β ≠ 0. Use results from the null distribution of simulated slopes shown to determine the standardized statistic.
