Step-by-step explanation:
Answer:
a)n=543
b)n=1509
c)n=13573
Step-by-step explanation:
a)
c=98%,
Margin Error
but
where the confidence level is 1-α=0.98
cross multiply
where p=0.5
input the values
n=0.33
b) E=0.33
confidence level
n=(2.33/0.33)²×0.5(1-0.5)=1504
c)
1-α=0.98
cross multiply
Zα/2=2.33
p=0.5
n=(2.33/0.01)²×0.5(1-0.5)=13573

The sample of sizes 2 and their mean are given below.
Step-by-step explanation:
The population consist of 5 values, S = {1, 3, 4, 4, 6}.
The number of samples of size 2 (without replacement) that can be formed from these 5 values is:
