A random sample of 150 people was taken from a very large population. About 100 of the people in the sample were female. The standard error of the proportion is?
Homework Answers
Number of Items of Interest,x =100
Sample Size,n = 150
Sample Proportion , p̂ = x/n = 100/150 = 0.6667
Standard Error , SE = √[p̂(1-p̂)/n] = √(0.6667 * (1 - 0.6667) / 150) = 0.0385

uppose that the proportion of successes in a population is ? and that a very large simple random sample of size ? is obtained from that population. What does the central limit theorem say about the distribution of the sample proportion? The sample proportion has mean equal to ? and standard deviation equal to ?(1−?)?⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯√. The sample proportion is approximately normally distributed if the sample is large enough. The sample proportion is binomially distributed with parameters ? and ?. The...
