We need to use the formula to find Margin of Error but through the sample proportion, that is
We will use a 95% confidence interval, that is a z value of 1.96 (Search in a Normal distribution table)
A) For A our (proportion) is equal to 0.45. So applying the formula,
B) We make the same of point A, but change our proportion to 0.35
c) We need to calculate the SE through proportion for 0.1, that is
Then our Error is given by,
Answer: 25
Step-by-step explanation:
Since, Total creepy-crawly creatures = 20
Out of which 80% are flies and 20% are spiders,
Thus, the total flies = 80% of 20 = 16
And, The total spiders = 20% of 20 = 4
Also, we know that the number of legs of a spider = 8,
⇒ Total legs belong to spiders out of 20 creepy-crawly creatures = 4×8 = 32
Again, the number of legs of a fly = 6
Thus, the total legs belong to flies out of 20 creepy-crawly creatures = 6×16 = 96
Hence, Total legs = 32 + 96 = 128
