Question 974368: Thank you so much for the help. If you can show the work on the five problems I would greatly appreciate it. Thank you very much!!
1) Determine the regression equation for the data. Round the final values to three significant digits, if necessary. 5)
x 6 8 20 28 36
y 2 4 13 20 30
2)If two balanced die are rolled, the possible outcomes can be represented as follows.
(1, 1) (2, 1) (3, 1) (4, 1) (5, 1) (6, 1)
(1, 2) (2, 2) (3, 2) (4, 2) (5, 2) (6, 2)
(1, 3) (2, 3) (3, 3) (4, 3) (5, 3) (6, 3)
(1, 4) (2, 4) (3, 4) (4, 4) (5, 4) (6, 4)
(1, 5) (2, 5) (3, 5) (4, 5) (5, 5) (6, 5)
(1, 6) (2, 6) (3, 6) (4, 6) (5, 6) (6, 6)
Determine the probability that the sum of the dice is 11.
3)The regression equation for the given data points is provided. Graph the regression equation and the data points. 6)
^
x 3 5 7 15 16
y 8 11 7 14 20
y = 5.1 + 0.75x
4)Use the regression equation to predict the y-value corresponding to the given x-value. Round your answer to the nearest
tenth. 7) ^
Nine pairs of data yield the regression equation y= 19.4 + 0.93x. Predict y for x = 58.
5)Estimate the probability of the event. 3)
In a certain class of students, there are 9 boys from Wilmette, 5 girls from Kenilworth, 10 girls from Wilmette, 4
boys from Glencoe, 3 boys from Kenilworth and 6 girls from Glencoe. If the teacher calls upon a student to
answer a question, what is the probability that the student will be from Kenilworth?
