<u>Answer:</u>

a).

$\frac{9\times10^9}{3\times10^7} \\ \\\implies 3\times10^2 \\ \\\implies 300$

b).

$\frac{9.45\times10^7}{2.1\times10^2} \\ \\\implies 4.5 \times10^5 \\ \\\implies 45 \times 10^4$

c).

$\frac{7.5\times10^{-5}}{5\times10^{-2}} \\ \\\implies 1.5 \times 10^{-3}$

Answer:

Null and alternative hypotheses:

H0: p1 = p2

H1: p1 ≠ p2

To find the sample proportions, we have the following:

$p'1 = \frac{x_1}{n_1} = \frac{113}{3180} = 0.0355$

$p'2 = \frac{x_2}{n_2} = \frac{157}{3168} = 0.0495$

$p' = \frac{(x_1 + x_2}{n_1 + n_2} = \frac{113 + 157}{3180 + 3168} = 0.0425$

Calculate Z statistics:

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

$= \frac{(0.0355 - 0.0495)}{\sqrt{(0.0425*(1-0.0425) * (\frac{1}{3180} + \frac{1}{3168})}} = -2.764$

Z = -2.764

P-value = 0.00285

The pvalue is low.

Since the pvalue is low, reject null hypothesis, H0.

Conclusion:

There is strong evidence that patients experiencing the primary outcome is different for those receiving the treatment compared to those without

Faction Equivalent demcimal for 2.46

Paul [167]

Here is you're answer:

In order to find the answer you have to switch all the options into decimals to see which one is equivalent to 2.46!

$\frac{246}{1000}$
$\frac{246}{1000} = 246 \div 1000 = 0.246$
$2\frac{46}{1000}$
$2\frac{46}{1000} = \frac{1023}{500} = 1023 \div 500 = 2.046$
$2 \frac{23}{50} = \frac{123}{50} = 123 \div 50=2.46$ <-- You're answer.
$\frac{223}{500} = 223 \div 500 = 0.446$

Therefore you're answer is option C "2 23/50." Remember when wanting to find the decimal divide the numerator by the denominator after you convert the mixed number (if it's a mixed number) into a improper fraction!

Hope this helps!
