Answer:
542
Step-by-step explanation:
We are required to find the sample size at 98% confidence interval in this question
E = 0.04
P* = 20% = 0.20
n = p* x (1-p)(Zα/2÷E)²
α = 1 - 0.98
= 0.02
To get Critical value
= 0.02/2 = 0.01
The critical value at 0.01 is 2.33
Inserting values into formula:
O.2 x 0.8(2.33/0.04)²
= 0.8 x 0.2 x 58.25²
= 542.89
The value of n must be an integer therefore the answer is 542.
A is your answer hope this helps

Answer: The answer is as follows:
Step-by-step explanation:
Given that,
S = {a,b,c)
(a) All the permutations of S are as follows:
= 3!
= 3 × 2 × 1
= 6
- (a,b,c), (a,c,b), (b,a,c), (b,c,a), (c,a,b), (c,b,a)
(b) All 2-combinations of S are as follows:
= 3
