The correct answer is 56.8
Answer:
Step 1: Calculate the mean of the data—this is \muμmu in the formula.
Step 2: Subtract the mean from each data point. These differences are called deviations. Data points below the mean will have negative deviations, and data points above the mean will have positive deviations.
Step 3: Square each deviation to make it positive.
Step 4: Add the squared deviations together.
Step 5: Divide the sum by the number of data points in the population. The result is called the variance.
Step 6: Take the square root of the variance to get the standard deviation
Answer:
Step-by-step explanation:
Answer:
789
Step-by-step explanation:
8679/789 = 11
14 and 15 have no common factor except ' 1 ' ,
so the fraction 14/15 can't be simplified.
It's already in the simplest available form ("lowest terms").
