Step-by-step explanation:

the numbers of the yellow and white counters

= 288- 38 = 250.

the ratio of yellow to white = 1:4

so,

the numbers of the yellow counters =

1/(1+4) × 250 =1/5 ×250 = 50

the numbers of the white counters =

4/(1+4) ×250 = 4/5 ×250 = 200

and the numbers of the red counters = 38

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} }

We know that N = 250 n = 91, replacing:

fpc = \sqrt{\frac{250 - 91}{250 -1} }

fpc = 0.799

Now, the formula would then be:

SE  = \sqrt{\frac{p * (1 -p)}{n} }*fpc

Now replacing, knowing that p = 0.12

SE= \sqrt{\frac{0.12 * (1 - 0.12)}{91} }*0.799

SE = 0.0272

So the standard error of the proportion is 0.0272
