Population Distribution
-2.5
The graph at the right show the
frequency distribution of a
population with a population mean of
2.5 and a population standard
deviation of 3.
If samples of size 25 (n = 25) were
taken from the population which
graph would most likely be a good
representation of the distribution of
the sample means?

597

step-by-step explanation:

answer: 5 17/33 % (to the tenth)

step-by-step explanation:

he guessed: 34.5 pounds

actual weight is 32.7

there for he is off:

34.5 -32.7 = 1.8

32.7 is the 100%

1.8 represents %? of 32.7

therefore:

32.7   - 100%

1.8     -     x%

x= 1.8*100%/32.7% = 18*100%/327%

x=1800%/327%   = (5 165/327)%

to the tenth:

5 17/33 %

a)  

step-by-step explanation:

we have to remove the roots and then apply exponential formula.

given,

we know,

so, we get

hence the answer is-
