Answer:
98% confidence interval for the true population proportion of all New York State union members who favor the Republican candidate is 0.373±0.065, that is between 0.308 and 0.438
Step-by-step explanation:
Confidence Interval can be calculated using p±ME where
- p is the sample proportion of 300 union members in New York State who favor the Republican candidate (
)
- 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 98% confidence level (2.33)
- p is the sample proportion (
![\frac{112}{300}=0.373](https://tex.z-dn.net/?f=%5Cfrac%7B112%7D%7B300%7D%3D0.373)
- N is the sample size (300)
Then ME=[tex]\frac{2.33*\sqrt{0.373*0.627}}{\sqrt{300} }[/tex≈0.065
98% confidence interval is 0.373±0.065
The distance would be 21. to find the difference, add the absolute values so 12+9, which equals 21
102,650-82,400=20,250. The value of the home increased by $20,250.
Answer:
10/4 is the amount it takes
Step-by-step explanation:
Answer:
Step-by-step explanation:
According to question
α−d+α+α+d=−3ba
3α=−3ba
α=−ba
α2−dd+α2+αd+α2−d2=3a
3α2−d2=3ca
3b2a2−h2=3ca
d2=3b2a2−3ca=3b2−3aca2
α(α2−d2)=−da
−ba(b2a2−(3b2−3aca2))=−da
b(b2−3b2+3aca2)=d
−2b3+3ab=a2d
2b3−3abc+a2d=0
pls mark me as brainliest..
