Answer:
And rounded up we have that n=3382
Step-by-step explanation:
Previous concepts
A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Solution to the problem
In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 98% of confidence, our significance level would be given by
and
. And the critical value would be given by:
The margin of error for the proportion interval is given by this formula:
(a)
And on this case we have that
and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
Since we don't have prior information for the estimated proportion we can assume
. And replacing into equation (b) the values from part a we got:
And rounded up we have that n=3382
Answer:
The money receive by Paul is
.
Step-by-step explanation:
Given as :
The ratio of share of money among three people as
Stephen : Paul : Bridget = 3 : 4 : 2
The total money receive by Stephen and Bridget = ![\pounds 50](https://tex.z-dn.net/?f=%5Cpounds%2050)
Let The money receive by Stephen = 3 x
Let The money receive by Paul = 4 x
Let The money receive by Bridget = 2 x
Now, According to question
The total money receive by Stephen and Bridget = ![\pounds 50](https://tex.z-dn.net/?f=%5Cpounds%2050)
I.e 3 x + 2 x = ![\pounds 50](https://tex.z-dn.net/?f=%5Cpounds%2050)
i.e 5 x = ![\pounds 50](https://tex.z-dn.net/?f=%5Cpounds%2050)
∴ x =
x = ![\pounds 10](https://tex.z-dn.net/?f=%5Cpounds%2010)
So, The money receive by Stephen = 3 ×
= ![\pounds 30](https://tex.z-dn.net/?f=%5Cpounds%2030)
Let The money receive by Paul = 4 ×
= ![\pounds 40](https://tex.z-dn.net/?f=%5Cpounds%2040)
Let The money receive by Bridget = 2 ×
=
Hence The money receive by Paul is
. Answer
Answer:
true
Step-by-step explanation:
