Health care issues are receiving much attention in both academic and political arenas. a sociologist recently conducted a survey of citizens over 60 years of age whose net worth is too high to qualify for medicaid. the ages of 25 senior citizens were as follows: 60 61 62 63 64 65 66 68 68 69 70 73 73 74 75 76 76 81 81 82 86 87 89 90 92 calculate the standard deviation of the ages of the senior citizens to 2 decimal places

Standard Deviation = 9.75        

Step-by-step explanation:

We are given the following data:

n = 25

Ages: 60, 61, 62, 63, 64, 65, 66, 68, 68, 69, 70, 73, 73, 74, 75, 76, 76, 81, 81, 82, 86, 87, 89, 90, 92

Formula:

For sample,

where are data points, is the mean and n is the number of observations.

Mean =

Sum of square of differences = 2278.96

S.D =

the answer is 375 miles

step-by-step explanation:

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
