Question

Will this likely give an accurate estimate of this percentage?

Select from the drop-down menus to correctly complete the statement.
Lori's method islikely or not likely to give an accurate estimate of this percentage since she surveyed a randmly selected group of campers or she did not survey every camper from her camp.

Answer 1

1. Yes, it is likely to give an accurate estimate.

2. Lori's method is likely to give an accurate estimate of this percentage since she surveyed a randmly selected group of campers

Hope it helps!

Answer 2

Explanation:

Given that to find the estimate of campers who bring lunch, Lori adapted to random sampling.

Random sampling is the accurate, reliable method for estimate of population parameters provided samples are drawn strictly at random and sample size is reasonably high.

Here randomness is ensured and also 300 is a good sample size.

Hence this is likely to give an accurate estimate of this percentage of campers at her camp that bring their lunch.
