Final answer:
To analyze the relationship between minutes spent doing aerobics and calories burned, Carol needs to make a scatter plot and use regression analysis. She made several mistakes including forgetting to enter certain data points and entering the data incorrectly.
Step-by-step explanation:
In this scenario, Carol is investigating the relationship between the number of minutes spent doing aerobics and the number of calories burned. To analyze this relationship, she needs to enter the data into a calculator and make a scatter plot. Then, she should use the calculator's regression function to find the equation of the least-squares regression line and add it to the scatter plot. Based on the given options, Carol made multiple mistakes:
a) She forgot to enter the point (3, 14) into the regression calculator.
b) She forgot to enter the point (24, 125) into the regression calculator.
c) She incorrectly entered the minutes doing aerobics for d) and e).
By making these mistakes, Carol would not get accurate results and would not be able to analyze the relationship between the variables properly.
