Answer:
As sample sizes increase, the sampling distributions approach a normal distribution. With "infinite" numbers of successive random samples, the mean of the sampling distribution is equal to the population mean (µ).
Step-by-step explanation:
population variance =σ
sample variance=}[/tex]
where n is sample size
so as n increases ,}[/tex] decreases, so sample variance decreases

The student interchanged the calculations when finding the values of change in x and y;
The student may have started by 14-4 but started with 3-1 for change in x.
Answer:
x=8
x=-2
Step-by-step explanation:
∣x−3∣+4=9
= ∣x−3∣=5
<u>Positive term: (x-3)</u>
(x-3) = 5
Rearrange and Add up
x = 8
<u>Negative term: -(x-3)</u>
Multiply
-x+3 = 5
Rearrange and Add up
-x = 2
Multiply both sides by (-1)
x = -2
