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 = 
We know that N = 250 n = 91, replacing:
fpc = 
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: x<8
interval notation is ( -∞,8)
Step-by-step explanation:
x<8
interval notation is ( -∞,8)
Answer:
a) Given expression,
12% of 312
Since 100% of 312 = 312
⇒ 10% of 312 = 31.2,
⇒ 1% = 3.12
⇒ 2% = 2 × 3.12 = 6.24
So, 12% of 312 = 10% of 312 + 2% of 312
= 31.2 + 6.24
= 37.44
b) Given,
Total number of servings = 312,
The percentage of vitamin C in each serving = 12%,
Thus, the total amount of the vitamin C in 312 servings = 12% of 312


= 37.44,
Hence, the question can be asked about the total amount of the vitamin C.
Answer:
The answer is 43.87
Step-by-step explanation:
To find the answer, multiply 8 by 4 to get 32. Now divide 32 by 4 and you should get the answer 8. This will make sure that your answer is correct. And so 32 divided by 4 equals 8.
8*4
Multiply
Final Answer: 32
32/4
Divide
Final Answer: 8
