The Final examination scores for selected samples of Probability and Statistics students who took the course from three different instructors (Lecturers) from three different satellite campuses (Accra, Kumasi and Takoradi) are shown below; Lecturer A Lecturer B Lecturer C
83 90 85
60 55 90
80 84 90
85 91 95
71 85 80
At α = 0.05, test to see if there is a significant difference among the averages of the three groups. Show the complete ANOVA table

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
