Answer:
hello your question is incomplete below is the complete question
Find the minimum sample size n needed to estimate μ For the given values of c, σ, and E. c=0.98, σ=6.5, and E=22 Assume that a preliminary sample has at least 30 members.
Answer : 48
Step-by-step explanation:
Given data:
E = 2.2,
std ( σ ) = 6.5
c ( level of confidence ) = 0.98
To find the minimum sample size
we have to first obtain the value of
note : a can be found using this relation :
( 1 - a ) = 0.98 ----- equation 1
a = 1 - 0.98 = 0.02
hence: a/2 = 0.01
This means that P( Z ≤ z ) = 0.99 the value of z can be found using the table of standard normal distribution. from the table the value of z = 2.33
P( Z ≤ 2.33 ) = 0.99
To obtain the sample size n
n = = (6.88409)^2
Therefore n ≈ 48
Answer:
the additive inverse of a negative integer is a positive integer
Answer:
1
Step-by-step explanation:
If you divide anything by that same number, you will always get 1. For example, if m = 5, 5/5 would be equal to 1.
Answer:
So, The answer would be 1=k
Step-by-step explanation:
My step is to make a T-chart, as u make it put X on one side and Y on the other
So what i did was i put 0 for both of them because it had start at 0
then i followed the line to the dot as i did that It has 6,6 so then i figured out what multiply all those number and the answer was 1=k
And another way you could do it was to make 6,6 and fraction like 6/6 then divde them both and get 1=k
So you would put the answer as 1
thats it Answer-1
