Final answer:
The point estimate of the population standard deviation is 43.14.
Step-by-step explanation:
In order to calculate the point estimate of the population standard deviation, you can use the formula:
s = √(σxi2)
Given that σxi2 is 1863.34, plugging that value into the formula:
s = √(1863.34) = 43.14
Therefore, the point estimate of the population standard deviation is 43.14, rounded to three decimal places.
