Hello Sir/Ma'am, Please can you help with this problem if you have any idea. I am clueless. I will appreciation your help. Thank you.

Question 27 2 pts You will be using StatCrunch for problems 27-30. A colleague went to the lego.com website in February 2014 and recorded the number of pieces and sales prices for 157 Lego products listed there. The data for this problem is located in StatCrunch and named Lego Prices. QUESTIONS: 1. Which variable do you think makes more sense to use as the explanatory variable? v [ Select ] Pieces 2 Lego Set Name lakes more sense as the response variable? Price Lego Set #Question 28 7 pts You will be using StatCrunch for problems 27-30. A colleague went to the lego.com website in February 2014 and recorded the number of pieces and sales prices for 157 Lego products listed there. The data for this problem is located in StatCrunch and named Lego Prices. QUESTIONS: Copy the data into the Corr/ Regression applet (also called Least Square Regression applet). 1. Produce a scatterplot and comment on the association between the variables as revealed in the scatterplot. (Remember to comment on form, direction, and strength.) 2. Report the value of the correlation coefcient. 3. Explain what it tells you about the correlation between the two variables. Question 29 4 pts You will be using StatCrunch for problems 27-30. A colleague went to the lego.com website in February 2014 and recorded the number of pieces and sales prices for 157 Lego products listed there. The data for this problem is located in StatCrunch and named Lego Prices. QUESTIONS: 1. Determine the equation of the least squares regression line for predicting the price from number of pieces. Report this equation below (use appropriate notation) and round any decimals to three places. 2. Use the equation of the regression line to predict the price of a lego set with 783 pieces. (show your work) Question 30 3 pts You will be using StatCrunch for problems 27-30. A colleague went to the lego.com website in February 2014 and recorded the number of pieces and sales prices for 157 Lego products listed there. The data for this problem is located in StatCrunch and named Lego Prices. QUESTIONS: 1. Identify the slope of the regression line and ll in the banks in the statement below to interpret its meaning. The slope of the regression line predicting price based on the number of pieces is __________ , meaning that for every additional _______________ , the predicted price increases by __________________
