Answer:
6
Step-by-step explanation:
There are only 6 significant digits because in total there are 9 digits. We do not need the first 2 0's, so now we only have 7 digits. But the question is do we really need the last 0? The answer is no. No, you do not need the last 0 because we already know that it's .0049, and the 0 is just an extra.
So without all the insignificant 0's, the number would look like this:
13.0049
Answer:
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 138
Average = 32.6 inch
Population variance,

We have to find a point estimate for the population variance of the height.
The point estimate for the population variance is the population variance itself.

Thus, the point estimate of population variance is the population variance that is 2.8.
