Explanation:
Detailed explanation-1: -The standard error of the mean (SEM) measures how much discrepancy is likely in a sample’s mean compared with the population mean. The SEM takes the SD and divides it by the square root of the sample size. The SEM will always be smaller than the SD.
Detailed explanation-2: -In our question, we have 2=21, n=25 2 = 21, n = 25 . Therefore: SE=√21√50.
Detailed explanation-3: -Calculate the mean of the total population. Calculate each measurement’s deviation from the mean. Square each deviation from the mean. Add the squared deviations from Step 3. More items •14-Feb-2023
