Answer with explanation:</h2>
Consider a sampling distribution with p equals 0.12 and samples of size n each.
Then, formula for mean = p
Formula for standard deviation= 
(a) For a random sample of size n equals 5000.
Mean = 0.12
Standard deviation= 

(b) For a random sample of size n equals 1000.
Mean = 0.12
Standard deviation= 

(c) For a random sample of size n equals 500.
Mean = 0.12
Standard deviation= 

Answer:
aₙ = a₁ + (n-1)d
where:
aₙ = nth term
a₁ = first term
d = common difference
The sequence 8,9,10,-10 is not an arithmetic sequence.
Step-by-step explanation:
x = the unknown number

nine <u>times</u>(multiplication) a number(x) divided(division) by 2 equals(=) 54,
so 9x is divided by 2
The Answer for "X" is going to be 25.63201, rounded to the nearest tenth would be 25.6.
I hope this helped :)
