Answer:
<u>The standard error of distribution for n = 4 is 5 and for n = 25 is 2.</u>
Step-by-step explanation:
1. Let's review the information given to us for solving the question:
Population mean = 72
Standard deviation = 10
Sample₁ = 4
Sample₂ = 25
2. For finding the standard error of the mean, we use the following formula:
Standard error = Standard deviation / √Size of the sample
Standard error for Sample₁ = 10/√4
<u>Standard error for Sample₁ = 10/2 = 5</u>
Now, let's find the standard error for Sample₂
Standard error for Sample₂ = 10/√25
<u>Standard error for Sample₂ = 10/5 = 2</u>
Answer:
50°
Step-by-step explanation:
<u>The sum of a triangles' angles is 180°</u>
Now set up an equation:
180 - (10 + 120) = ___
180 - 130 = 50°
is the slash supposed to be division or a fraction?
Answer:
Step-by-step explanation:
$72 is 100% and
$? is 16%
? = 16*72/100 = 11.52
Answer:
range = 55-17
= 38
Step-by-step explanation:
to find the range, subtract the smaller number in the data from the bigger number.
