Answer:
The first error she made in computing the variance was to have placed -1,024 instead of +1,024
Step-by-step explanation:
we have the data set
87, 46, 90, 78, and 89
step 1
Find the mean
step 2
Subtract the Mean for each value of data set and square the result and then adds the numbers
so
The first error she made in computing the variance was to have placed -1,024 instead of +1,024
step 3
Work out the mean of those squared differences
----> this value is called the "Variance"
