Let's say you scored a 111 on Exam 1 and you scored a 125 on Exam 2. You can predict your final exam score with the following prediction equation: Y' = bX + c (round to the nearest whole number). X is the total number of points you earned on the first two tests. Given: Mean =120, Standard deviation = 100. The correlation (r) between the total score on the first two exams and the final is 0.89, b = 0.5567 and c =4. How likely (denoted as a percentage) is it that you will score less than a score of 111 on the final exam?

1.500 University student's exam scores are determined at the end of the semester. Patty scored 850 marks (X) in total out of 1000. The average score for the tests was 725 (u) and the standard deviation was 180 (a). Let's find out how well Patty scored compared to her peers. Using the above data we need to first standardize his score and use the respective 2-table to determine how well he performed compared to his batch mates. To find out...

1a) Let's say that you made a scatterplot for bivariant data such that the x-values ranged from 50 to 85. From this, you successfully created a linear regression equation. Why should you not use the equation to make predictions of the y-value with x = 20 but you can for x = 60? b) Let the coefficient of determination be 0.81. If you were provided no additional information, what is one thing you can determine about the correlation coefficient and...

In a study, the following equation for predicting a child’s
metabolic rate (in 100 kcal/24h) (Y) given his/her weight (in
kilograms) (X) is found: Y = 0.4X + 0.89. The RMS for the
prediction is 1.144 (in 100 kcal/24h). What is the probability that
a child that weighs 15 kilograms has metabolic rate exceeding
8?
