Need help with part C of the question only.

Inference on the Slope of Facebook Friends and the Brain Computer output for a regression line to predict the number of Facebook friends a student will have, based on a normalized score of the grey matter density in the areas of the brain associated with social perception and associative memory is given below. Data for the sample of n = 40 students are stored in FacebookFriends. Pearson correlation of GMdensity and FBfriends = : 0.436. P-Value = 0.005. The regression equation is FBfriends 367 + 82.4 GMdensity.

(b) Use the information from part (a) to calculate the test statistic to test the slope to determine whether GMdensity is an effective predictor of FBfriends. Find the test statistic and p-value and make a conclusion. Round your answers to three decimal places. t = 2.99 The p-value is i .005 Conclusion: Reject O Ho. eTextbook and Media (c) Use the information from part (a) to find a 95% confidence interval for the slope. Uset-values rounded to three decimal places. Round your answers to two decimal places. i to i
