Standard error for a sample proportion, p = 0.8, n = 1200
Answer:
Final answer is 123.
Step-by-step explanation:
Given that there are 820 people at a stadium.
Out of which 65% are adults, 20% of them are boys, and the rest are girls.
Now we need to find about how many girls are there at the stadium?
We know that total percent can be 100%
So percentage of girls in the stadium = (Total %) - (Adults %) - (Boys %)
= 100% - 65% - 20%
= 100% - 85%
= 15%
Then total number of girls at the stadium = 15% of 820
= 0.15 ( 820)
= 123
Hence final answer is 123.
The final answer/value of x is 6.
25 - 21 = 4 questions of his history incorrectly ;
4 / 25 = 0.16 represents the fraction of problems he answered incorrectly ;
