A sociologist recently conducted a survey of citizens over 60 years of age who have net worths too high to qualify for Medicaid
but have no private health insurance. The ages of the 25 uninsured senior citizens were as follows: 68 73 66 76 86 74 61 89 65 90 69 92 76
62 81 63 68 81 70 73 60 87 75 64 82
Find the upper quartile of the data.
a) 65.5
b) 92
c) 81.5
d) 073
H ( x ) = - 6 + x m = 1 ( the slope ) b = - 6 ( y - intercept ) x - intercept: 0 = - 6 + x x = 6 The graph is going through Quadrants: I, II and IV. Answer: B ) Quadrant II, because the slope is positive and y-intercept is negative.
