Step-by-step explanation:
n = 0
because,
p^0 = 1
10000000^0 = 1
Answer:
![x=37.5](https://tex.z-dn.net/?f=x%3D37.5)
Step-by-step explanation:
We need to find the solution to the following system of equations:
and ![y=-30](https://tex.z-dn.net/?f=y%3D-30)
By plugging the value of 'y' into the first equation we have that:
⇒ ![30=\frac{4}{5} x](https://tex.z-dn.net/?f=30%3D%5Cfrac%7B4%7D%7B5%7D%20x)
Solving for 'x' we have:
![x=37.5](https://tex.z-dn.net/?f=x%3D37.5)
So, the solution to the system of equation is: (37.5, -30)
Answer:
a. Best estimate for the mean family size for the population of all families in a country is 16.3571428571
b. 95% confidence interval for the estimate is 16.3571428571±0.7106240840. That is between 15.6465187731 and 17.0677669411
c. The sample is unlikely to be very representative of all families in a country.
Step-by-step explanation:
a. mean family size for the population of all families in a country can be estimated as sample mean, and calculated as:
≈ 16.3571428571
b. 95% confidence interval for the estimate can be calculated using the equation CI=M±
where
- M is the mean estimate (16.3571428571)
- t is the corresponding statistic in the 95% confidence level and with 14 degrees of freedom (2.160)
- s is the standard deviation of the sample (1.2309777100)
- N is the sample size (14)
s can be calculated as square root of mean squared differences from the sample mean.
Thus 95% CI=16.3571428571±
≈ 16.3571428571±0.7106240840
The sample is unlikely to be very representative of all families in a country because as the sample data increases, estimate will improve.
