A random sample of 10 subjects have weights with a standard deviation of 9 8753 kg What is the variance of their weights? Be sur

hammer [34]

Answer: The variance of their weights = 9,752,155,009 kg.

Step-by-step explanation:

The variance is the square of the standard deviation . it measures the spread between data values in a data set.

So if standard deviation of 10 subjects = 98753 kg

Then, variance = $(9 8753 )^2\ kg=9,752,155,009\ kg$

Hence, the variance of their weights = 9,752,155,009 kg.
