The data is Income (available in the quiz directions), have two variables, consumption, andIncome (in 1,000 dollars). We want to predict consumption based on Income, i.e., Income isthe independent variable.Use Excel to calculate the regression equation to answer the question.The 85% confidence interval for the slope is:O (0.430997, 0.753221)(0.3683183, 0.8158995)O(0.40670, 0.77752)O (0.32167, 0.86255)(0.39397, 0.79025)O (0.24305, 19.30748)

To answer your question, based on the confidence interval provided, the correct option is:(0.430997,…

Answered: The data is Income (available in the…

At one of the San Diego area beaches, there has been a problem with thefts in the summer months. A random sample of summer days was selected. For each day, the number of street cameras (X) in the beach area and the number of reported thefts (Y) were recorded. The data was analyzed to produce the results below: The regression equation is: Thefts = 9.78 – 0.493*(cameras) On a certain day there were 5 cameras in the area and 3 reported thefts. Calculate the residual for this day. 8.301 -4.315 4.315 3.301 7.315
