Answer:
the standard error of the proportion is 0.0272
Step-by-step explanation:
We have that if the sample size is greater than 5% of the entire population, a finite population correction factor (fpc) is multiplied with the standard error
:
fpc = ![\sqrt{\frac{N -n}{N -1} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7BN%20-n%7D%7BN%20-1%7D%20%7D)
We know that N = 250 n = 91, replacing:
fpc = ![\sqrt{\frac{250 - 91}{250 -1} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B250%20-%2091%7D%7B250%20-1%7D%20%7D)
fpc = 0.799
Now, the formula would then be:
SE =
*fpc
Now replacing, knowing that p = 0.12
SE=
*0.799
SE = 0.0272
So the standard error of the proportion is 0.0272

Answer:
19.25 ft
Step-by-step explanation:
for every one cm the actual car is 2.5 feet. therfore it would be 7.7 times 2.5 which equals 19.25
