Use the applet to select 20 different random samples of 100 part-time college students. For each sample the applet calculates the 95% confidence interval. How many of the 20 random samples do not contain the population proportion
Population: PT college students
Percent female: p = 0.60
Sample Proportion = p = 0.63
Sampling distribution: approx. normal
mean =.60 sd = v(.60)(1-.60)/100 = 0.049
95% Confidence Interval (z* -2.0)
lower limit 0.63-2.0*0.049 0.53
upper limit 0.63+2.0*0.049 0.73
margin of error = 2.0(0.049) = .098
0.53 p = 0.63 0.73
0.0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0
