Answer:
So Equation(1) and Equation(2) both are not same C.I hence the given statement is false.
Step-by-step explanation:
Given:
total member =2000
Favor member=1600
Mean=1600/2000=0.8
To Find:
C.I of 95 % and it is true for given statement
Solution:
Now to calculate the
C.I=0.8±Z*Sqrt[p(1-p)/n]
C.I=0.8±1.96Sqrt[0.8(0.2)/2000]
C.I=0.8±0.0175
C.I=0.7825 to 0. 8175 .........Equation(1)
Now
Above C.I should be same when n =100 and x= 80 So p=x/n=80/100=0.8
Hence
C.I.=p±Z*Sqrt[p(1-p)/n]
C.I=0.8±1.96*sqrt[0.8*0.2/100]
=0.8±1.96*0.04
=0.8±0.0784
Hence C.I.=0.7216 to 0.8784............Equation(2)
By comparing
So Equation(1) and Equation(2) both are not same C.I hence the given statement is false.
There are 13 clubs and 52 cards for a probability of 13/52= 1/4 for the first card being a club...
Total of 6 numbers: 360
1 number: 30
Total of the other 5 numbers: 360 - 30 = 330
The average of the x numbers is the sum of the numer diveded by "x", so:
330 divided by 5 = 66.
The average of the other 5 numbers is 66
First off, we'll move the non-repeating part in the decimal to the left-side, by doing a division by a power of 10.
then we'll equate the value to some variable, and move the repeating part over to the left as well.
anyhow, the idea being, we can just use that variable, say "x" for the repeating bit, let's proceed,
and you can check that in your calculator.
