standard deviation of the sample data is 12.42801
Step-by-step explanation
Sales volume last weekend for a sample of ten car dealerships is given
# Sales 44 12 20 49 23 30 34 21 14 36
Now we have to calculate standard deviation of the sample data
we know the formula for standard deviation
here n =10
s = ?n−1∑(xi−x?)2??? = ??91390.10???? = ?1?54.4556?
s = 12.42801
standard deviation of the sample data is 12.42801
