Hello, so in part a, our mean x bar, that's going to be the sum of all the x values divided by n.
00:08
So here that's 59 plus 85, plus 98, plus 106, plus 120, plus 117, plus 95, plus 143, plus 371, plus 14, plus 15.
00:18
That's going to give us our 1 ,320, and then we have 12 values divided by 12, giving us that x bar, our mean, is 110.
00:27
And 10.
00:28
And then we put for part b, our data in ascending order.
00:33
We get the two middle values are 97 and 98...
