Eastern States Standard deviation = 6440.2
Western States Standard deviation = 16178
The Western States is more variable because it has a higher deviation. Also you can tell that the Western States is more variable because the the data/numbers change more than the Eastern States.
Answer:
a) 97.37%
b) 1.31%
Step-by-step explanation:
a)
Here we want to calculate the area under the Normal curve with mean 0.52 and standard deviation 0.009 between 0.5 and 0.54
This can be easily done with a spreadsheet and we get
<em>P (0.5くV < 0.54) = 0.9737 or 97.37%
</em>
(See picture 1)
b)
Here we want the area under the Normal curve with mean 0.52 and standard deviation 0.009 to the left of 0.5.
<em>P(V ≤ 0.5) = 0.0131 or 1.31%
</em>
(See picture 2)
The formula for standard deviation is in attachment the mean (or average is subtracted from each data sample then squared, then summed up for all data samples, then divided by the number of samples, then finally the square root is taken.
The first row of data will have a standard deviation of 0.
The second row of numbers will have a low standard deviation because the differences between the sample data values are low ( <10).
The third row of number will have a somewhat larger standard because of the spread of the numbers.
The last row will have a slightly smaller standard deviation that the 3rd row because of the zero's
What smaller number can you get other than 0?
The first row of data has a 0 or smallest standard deviation
Answer:
In this problem it gives you the equation you need to solve it.
Y=10x+190
The question asks for the number of calories if the snack has 35 grams of fat. The grams of fat is the independent variable so it is going to be x. So just substitute the x in the equation with 35.
Y=10×35+190
Y=350+190
Y= 540
So for a snack that has 35 grams of fat, it would have 540 calories.
