An office uses 478 pounds of paper in one week. The paper comes in packages that hold 18 pounds of paper each. How many packages

ddd [48]

To solve this, you would divide 478 by 18, which equals 26.5555556. Since you can't have half a package of paper, the answer would be 26. Hope this helps!

An international polling agency estimates that 36 percent of adults from Country X were first married between the ages of 18 and

alukav5142 [94]

Answer:

(B) 0.2843

Step-by-step explanation:

Let d be the difference in proportions from Country X and Country Y who were first married between the ages of 18 and 32.

Then hypotheses are

$H_{0}$ : d=0.15

$H_{a}$ : d<0.15

Test statistic can be found using the equation

$z=\frac{p1-p2-0.15}{\sqrt{{p*(1-p)*(\frac{1}{n1} +\frac{1}{n2}) }}}$ where

p1 is the sample proportion of Country X (0.36)

p2 is the sample proportion of Country Y (0.26)

p is the pool proportion of p1 and p2 ( $\frac{60*0.36+50*0.26}{50+60}=0.31$ )

n1 is the sample size of adults from Country X (60)

n2 is the sample size of adults from Country Y (50)

Then $z=\frac{0.36-0.26-0.15}{\sqrt{{0.31*0.69*(\frac{1}{60} +\frac{1}{50}) }}}$ ≈ 0.5646

p-value of test statistic is ≈ 0.2843

p-value states the probability that the difference in proportions between a random sample of 60 adults from Country X and a random sample of 50 adults from Country Y who were first married between the ages of 18 and 32 is at least 0.15

Suppose that true average price of a beer at professional sporting events in the US is $6. You attend 34 events and find an aver

aniked [119]

Answer: The standard error for sample is 0.0686 .

Step-by-step explanation:

We know that the formula to find the standard error is given by :-

$S.E.=\dfrac{s}{\sqrt{n}}$

, where s = standard deviation

n= Sample size

As per given , we have

s= $0.4 and n= 34

Then , the standard error for sample is given by :-

$S.E.=\dfrac{0.4}{\sqrt{34}}=\dfrac{0.4}{5.83095189485}\\\\=0.0685994340569\approx0.0686$

Hence , the standard error for sample is 0.0686 .
