With the following information

A survey of 10 graduates

5 Literature Major Graduates make between $30,000-$31,000

3 Technology Graduates make $40,000

2 Computer Science Graduates make $45,000

a. Point estimate

mean_income

sum(XI*Fi)/sum(Fi)

36250

b. Confidence Intervals

mean+-z(a/2)*sd/sqrt(n))

sd= sqrt {sum(Xi^2*Fi)/sum(Fi) - mean^2}

6005.206075

lower 32527.93471 upper 39972.06529

I am 95% confident that estimated income lies in this interval

Xi Fi Literature Major Graduates 30500 5

Technology Graduates 40000 3

Computer Science Graduates 45000 2
