The weight of ripe pumpkins grown at Mr. Mike's farm are normally distributed with a mean of 8 pounds and a standard deviation of 2 pounds. The Interquartile Range (IGR) is Q3-Q1. Find the IQR of Mr. Mike's pumpkins. Make sure to show all of your calculations and explain.
So I know that in a normal distribution, the mean median and mode are all equal and are at the 50% percentile I believe. So it is a normal curve with 8 in the middle, and I increase at an interval of two to the right, and decrease at an interval of 2 to the left, however I don't know how many intervals to put? I believe its 3 but I'm not positive. If it is 3, how would I find q1 and also q3 from the distribution? any help is appreciated.
Re: Completely Stumped by Impossible Stat Question
Do you know how to find any percentiles? It's a basic idea taught in intro stats courses and I'm assuming that you've had to have been taught how to do this (at least for the standard normal distribution). I'll also note that this questions is FAR from impossible so your title isn't quite accurate
