MATH 1280 Self-Quiz Unit 7 (100%) – University of the People Grade 10.00 out of 10.00 (100%) Information text Recall that the population average of the heights in the file "" is μ = 170.035. Using simulation it can be shown that the probability of the sample average of the height falling within 2 centimeter of the population average is approximately equal to 0.925. From the simulations we also got that the standard deviation of the sample average is (approximately) equal to 1.122. In the...
