<u>burned: </u>756 calories
<u>hours:</u> 3
same number of calories each hour
-> to find this, we must split the number of calories evenly among the hours
<u>steps</u>
756/3
= 252 calories per hour
The answer is 3/2
3 units up and 2 units to the left that is the slope
Let get all the information.
Mean:394
Deviation:35
Looking for At Least 380 feet
To find the z score you take the wanted probality subtract the mean and divide by the deviation.
z=(380-394)/35.
z=-0.4
So far so good.
But when he looked at the table he looked at probability that the home runs are less then 380 feet.
From this table
http://www.stat.ufl.edu/~athienit/Tables/Ztable.pdf
To find the answer you have to take 1-(the probability that the home runs are less than 380 feet)or 1-0.3446=0.6554
He made an error in his calculation.
Add 2 3/4 and 2 1/2 and you’ll get ur answer. area means total and when u see area, it means add
D because on the Y-axis it’s going to always be 5
