Consider a normal distribution of frog weights with μ= 500 grams and σ= 65 grams. A sample size of 2,000 is drawn from this population. Approximately how many of the 2,000 cases would you expect to find between 435 and 565?

Question

sdfgsdfgs · Answer

Given μ= 500 grams and σ= 65 grams
so 435 and 565 are exactly within one σ from μ
For normal distribution, approximately 68% of sample value will fall within that range.

You should be able to figure out the exact number from here. Good luck!

Welcome...although u may want to read up on Normal Distribution before doing more hw on that. The 68% figure is really basic for normal distribution.
