Making Inferences Based on Statistics Objective In this lesson, you will Sample Mean and Sample Proportion To find the sample mean, the values in the sample and then by the sample size. The sample mean is represented by the symbol x: X = - sum of values in the sample sample size To find the satpple proportion, the number of values in the sample that meet some criterion and by the sample size. The sample proportion is denoted by p: p = - number of values in the sample the meet a criterion sample size Calculate the mean of this data set: 12, 35, 44, 74, 23, 49, 45, 18, 90, 56, 84, 38, 7. What is the sample proportion of numbers that are within 10 of the mean? The mean is the sum of all observations divided by the number of observations. To calculate the sample mean, use the sample mean formula. sum of values in the sample sample size 12 + 35 + 44 + 74 + 23 + 49 + 45 + 18 + 90 + 56 + 84 + 38+7 13 575 13 ~44 The sample mean is rounded to the nearest integer, which is 44.
