Attendance and Tests
Data were collected that included information on the number of first-grade students in different sections who are present in one week and the number of tests in that week.
The figure shows a scatterplot with the regression line.
a. Is the trend positive or negative? What does that mean?
b. Now calculate the correlation between the number of present students and the number of tests in that week. (Use R-Sq from the figure and take the square root of it.)
c. Report the slope. For each additional test on a day, there are, on average, how many students present?
d. Either report the intercept or explain if it is appropriate to interpret it or not.
DAY 1. Multiply the three matrices together in order (A*B*C) to get a fourth matrix 'D'. What is the fourth matrix? DAY 2. Multiply the fourth matrix by the scalar 6 to get a fifth matrix E.
a. Find the distribution of the project duration. Report the mean and the standard deviation. b. If the project duration exceeds 250 days, a penalty will be assessed. What is the probability that the project will be completed within 250 days?
