Bill is better bowler than George.
To decide who's the relative better bowler, George or Bill, I've first drawn bell curves for each of their leagues. George's league is in red mean is 150 a standard deviation of 20. And Bill's League Demean is higher at 160, but the standard deviations it is lower at 15, so I've numbered my bell curve by 15.
Now to decide who's relative better bowler, I'm going to calculate their Zscores for George, His observed value is 180, which would fall right here on our number line, and his Z score is gonna be 180- the mean. So he's 30 points above the mean, Divided by the standard deviation (180-150)/20=1.5 And then for bill, we're going to do the same thing. His score is also, let's see here his score is 190,(190-160)/15=2And you can probably see just by marking that on the bell curve, that that's actually two standard deviations above the ME, which is more than George is 1.5 standard deviations above the mean. So we can say that Bill is better bowler.

Step-by-step explanation:
Given that standing on one side of the Mississippi River, you notice a tall tree directly across from you on the opposite bank. You walk 2000 meters along the bank and the tree is still visible, but at an angle of 65° to the bank
Visualise the right triangle formed by the river directly across in the first position , 2000 metres the distance walked along the bank and the line (here hypotenuse) joining you new position and the vertex opposite the bank
We have 65 degress angle has opposite side as width of river and adjacent side as 2000 m
Using trignometrical ratio
we get
