Just before a referendum on a school​ budget, a local newspaper polls 402 voters to predict whether the budget will pass. Suppos
Sliva [168]

Answer:

21.21%

Step-by-step explanation:

Assume that proportion of support follows normal distribution.For resulting in defeat the proportion of support should less than 0.5.Given that the proportion of support is p= 0.52.

Sample size(n)= 402

We know that standard deviation is given as

\sigma = \sqrt {\dfrac {p(1-p)}{n}}

Now by putting the values

\sigma = \sqrt {\dfrac{0.52\times 0.48}{402}}

σ=0.0249

Proportion of support follows normal distribution with mean is 0.52 and standard deviation is 0.0249

We know that Z=\dfrac{\bar{X}-\mu }{\sigma }

So

Z=\dfrac{0.5-0.52 }{0.0249}

Z= -0.80

So P(Z<-.80) =0.2118 from standard table.

So the probability of news paper to predict defeat is 21.21%

Carbon–14 is a radioactive isotope that decays exponentially at a rate of 0.0124 percent a year. How many years will it take for
patriot [66]
100-0.0124=99.9876

10%=1/10
1/10P=P(0.999876)^t
divide both sides by P
1/10=0.999876^t
take ln of both sides
ln(1/10)=t (ln(0.999876))
divide both sides by (ln(0.999876))
ln(1/10)/(ln(0.999876))=t
use calculator
18568.08=t
about 18568 years
