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 (\frac{112}{300}=0.373)
  • ME is the margin of error from the mean

and margin of error (ME) around the mean can be found using the formula

ME=\frac{z*\sqrt{p*(1-p)}}{\sqrt{N} } where

  • z is the corresponding statistic in 98% confidence level (2.33)
  • p is the sample proportion (\frac{112}{300}=0.373
  • 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

Use inverse operations to love each equation--
Dominik [7]

a.) you start with 19=h/3-8 so you add 8 to both sides then you simplify 19+8 to 27 so the equation then becomes 27=h/3 from there you multiply each side by 3 so its 27*3=h then you simplify 27*3 which leaves you with 81=h u then switch it around and your final answer h=81

b.) you start with 0.6x +0.8=1.4 first you subtract 0.8 from both sides so the equation is 0.6x=1.4-0.8 then you simplify 1.4-0.8/ so it then becomes 0.6x=0.6 u then divide both sides by 0.6 so the equation is now x=0.6/0.6 you then simplify 0.6/0.6 so you are left with x=1

Explain why the amount of money in the account at the end of t years is given by the formula: P=P0(1+r/n)^nt
miskamm [114]
This is the formula you use for someone investing in money. The formula is actually supposed to be: <em>A</em>=P(1+\frac{r}{n})^{n(t)}.
A is the total amount, P is the principal amount (the initial; original), r is percent (%) rate in decimal form, n is frequency, and t is the amount of years.
