10:25 Probability and Samples HW FA21 PSYZBIO, Statistical Methods of Psychology, Fall 2021 Homework, Chapter 7, Probability and Samples For Ill and #2, calculate the proportions. You are given the correct answers. You will need to show all of your work starting with equations, and ending in an explanation of how you found ,o. Example of explaining how you found p: "The proportion is .30. which is the proportion in the body for z I +0.85 in the unit normal table.\" A population of scores forms a normal distribution with a mean at u = 70 and a standard deviation of a = 20. 1] If samples of n I 4 are selected from the population. what proportion of the samples will have means less than M = 80? The answer to this isp = .841 2] If samples of n I 16 are selected from the population, what proportion of the samples will have means less than M = BO? The answer to this is p = .97? Important: I All of your work should start with the appropriate lormulas, Each problem requires two lormulas to solve it. I You do not need to construct a table with scores, deviations, and squared deviations to solve these problems
