you can easily solve this by using a rule of three
Step one
if
45 gal⇒ 375 lb
62 gal ⇒ x lb?
do the relation

Step 2: x = 36 + 12
Step 3: x = 24
Which statement best explains why Step 2 is incorrect in Skyler's solution?
Answer:
Step 2 is incorrect.
Step-by-step explanation:
It's incorrect because I'm pretty you need to do inverse operation. To get 24 you must subtract, not add.
Answer:
Mean increase or decrease (same quantity) according to the quantity of the increment or reduction
As all elements were equally affected the standard deviation will remain the same
Step-by-step explanation:
For the original set of salaries: ( In thousands of $ )
51, 53, 48, 62, 34, 34, 51, 53, 48, 30, 62, 51, 46
Mean = μ₀ = 47,92
Standard deviation = σ = 9,56
If we raise all salaries in the same amount ( 5 000 $ ), the nw set becomes
56,58,53,67,39,39,56,58,53,35,67,56,51
Mean = μ₀´ = 52,92
Standard deviation = σ´ = 9,56
And if we reduce salaries in the same quantity ( 2000 $ ) the set is
49,51,46,60,32,32,49,51,46,28,60,49,44
Mean μ₀´´ = 45,92
Standard deviation σ´´ = 9,56
What we observe
1.-The uniform increase of salaries, increase the mean in the same amount
2.-The uniform reduction of salaries, reduce the mean in the same quantity
3.-The standard deviation in all the sets remains the same.
We can describe the situation as a translation of the set along x-axis (salaries). If we normalized the three curves we will get a taller curve (in the first case) and a smaller one in the second, but the data spread around the mean will be the same
Any uniform change in the data will directly affect the mean value
Uniform changes in values in data set will keep standard deviation constant
The mean salary is affected by each employee's changes in salary, such as raises and pay cuts, but the standard deviation (the spread of salaries) remains the same provided the change is the same for all individuals.
To answer this question, we need to calculate the sample mean and sample standard deviation in each case. The sample mean is the average of the data, while the sample standard deviation is a measure of the amount of variation or dispersion in the data set.
