Answer:
95% confidence interval for the true fraction p is (0.426, 0.488)
Step-by-step explanation:
Confidence Interval can be calculated using p±ME where
- p is the sample proportion (
- ME is the margin of error from the mean
and margin of error (ME) around the mean can be found using the formula
ME= where
- z is the corresponding statistic in 95% confidence level (1.96)
- p is the sample proportion (0.457)
- N is the sample size (1000)
then ME= ≈ 0.031
Then 95% confidence interval would be 0.457±0.031 or (0.426, 0.488)
Answer:
1x - 1
Step-by-step explanation:
So first you distribute; and that should give you 1x - 1
Answer: 32
Step-by-step explanation:
All you have to do is is multiply 8 by the numbers in the parentheses. So you multiply 8 by 3, which equals 24. Then multiply 8 by 4, which is 32. Hope this helps! :)
This answer is an solution if you add 34+12 then it equals to 46
