I have a list:
85 45 75 60 90 90 115 30 55 58 78 120 80 65 65 140 65 50 30 125 75 137 80 120 15 45 70 65 50 45 95 70 70 28 40 125 105 75 80 70 90 68 73 75 55 70 95 65 200 75 15 90 46 33 100 65 60 55 85 50 10 68 99 145 45 75 45 95 85 65 65 52 82
Sorry for the poor formatting, but I created a program that would count the frequencies, etc. and I still am getting the problem wrong.
The class width should be 28 since the problem specified that it needed to be divided into 7 classes.
The class limits make sense to me since the smallest value is 10 and you just need to add 28 (the class width), and the next should be 48, right? Or am I completely off base?
Class boundaries will make sense once I get the right values for the class limits.
The midpoint should be the lower limit + the upper, so wouldn't the midpoint of (10 + 38)/2 be 24??
And relative frequency is just the frequency divided by the total frequencies, right?
So might you know why the class limits aren't 48-76, etc.? I'm trying to figure out how to work this frequency table. Thanks for your help :/
