Estimate the population proportion of IS based in the follow

#2 As the old saying goes, \"It either it IS or it AINT.\" Estimate the population proportion of IS based on the following sample: = .10 IS 99 point estimate = critical value- bound lowest. high est. = AINT= 59 n= st.error Splaynit

Solution

n = 158

point estimate = 99 / 158 = 0.6266

critical value for alpha = 0.10

critical value : 1.64

St error = srqt( [ 0.6266*(1-0.6266)] / 158 )

St error = 0.038

bound : 0.6266 +/- 1.64 * 0.038

bound : 0.6266 +/- 0.06

low : 0.5666

high : 0.6866
