A professor in the School of Business in a university polled a dozen colleagues about the number of professional meetings they attended in the past five years (x) and the number of papers they submitted to refereed journals (y) during the same period. The summary data are provided. Fit a simple linear regression model between x and y by finding out the estimates of intercept and slope. Comment on whether attending more professional meetings would result in publishing more papers. n n n = 12, x = 4, y = 11, Σx² = 237, Σx¡y₁ = 313 i=1 i=1 The estimated regression line is ŷ = ☐ + ( 0 )x. (Round to two decimal places as needed.) Comment on whether attending more professional meetings would result in publishing more papers. Let it be unclear that attending more professional meetings affects the number of published papers if the value used to make that determination is between -1 and 1. Because the of the regression equation is it would appear that attending more professional meetings would result in publishing more papers. would result in publishing fewer papers. does not clearly affect the number of published papers.

A researcher knows that people with higher annual salaries commit fewer crimes. He is creating a regression model to predict the number of crimes a person will commit based on their salary Based on this information alone which of the following MUST be the slope of the regression line choose one 1.00 or 0.50 or -0.50
The slope of a regression line tells you how much or little a change in your dependent variable impacts your independent variable. O TrueO False

I’m taking a statistics and probability class. Please get this correct because I want to learn. I have gotten wrong answers on here before
A regression analysis was performed to determine if there is a relationship between hours ofTV watched per day r) and number of sit ups a person can do (y). The results of the regression were: у-ах+b a=-0.827 b=35.329 r2=0.540225 r=-0.735 Use this to predict the number of sit ups a person who watches 13.5 hours of TV can do, and please round your answer to a whole number.
I need in one hour pls help thankyou
