Answer:
σ = 3.08
Step-by-step explanation:
Given
6, 5, 13, 8
Required
Standard Deviation
Take note of the following highlighted steps
1. Calculate the Mean
Mean = summation of data ÷ number of data
Summation = 6 + 5 + 13 + 8
Summation = 32
Number of data = 4
Mean = 32/4
Mean = 8
2. Subtract the mean from given data
6:-> 6 - 8 = -2
5:-> 5 - 8 = -3
13:-> 13 - 8 = 5
8:-> 8 - 8 = 0
We have; -2, -3, 5, 0
3. Square these results
-2:-> -2² = 4
-3:-> -3² = 9
5:-> 5² = 25
0:-> 0² = 0
We have: 4, 9, 25, 0
4. Calculate the mean of these results
Mean = summation of data ÷ number of data
Summation = 4 + 9 + 25 + 0
Summation = 38
Number of data = 4
Mean = 38/4
Mean = 9.5
Step 5: Take square root of the above
Standard Deviation, σ = √9.5
σ = 3.08220700148
σ = 3.08 (Approximated)
Answer:
The amount of flour Mrs.Stewart needs for 5 cups of shortening cups.
Step-by-step explanation:
Mrs.Stewart pie dough needs cups of shortening for cups of flour.
Now we assume that the shortening needed for cups of flour is cups.
Accordingly we can arrange the ratios.
So for one cup of shortening how many cups of flour is needed we have to use the unitary method:
Plugging the value of as it is number of cups of shortening Mrs.Stewart have used.
And multiplying both sides with .
Number of cups of flour needed when cups of shortenings are used .
So,
The amount of floor Mrs.Stewart needed for cups of shortening cups of floor.
