Mrrafil [7]

3/5÷1/7 use the recipical

3/5 ÷ 7/1= 21/5

21÷5=4 1/5 I think is your first answer but I could be wrong

7/8 6/7

you must find common denominator.

49/56 - 48/56= 1/56 again I could be wrong

Let n1=50, X1=10, n2=50, and X2=30. Complete parts (a) and (b) below. a. At the 0.10 level of significance, is there evide

iren2701 [21]

Answer:

|Z| = |-4.089| > 1.645 at 0.10 level of significance

Null hypothesis is rejected at 0.10 level of significance

There is a difference between the two Population proportions

Step-by-step explanation:

Step(i):-

Given first sample size (n₁) = 50

Given proportion of the first sample p⁻₁= 0.2

Given second sample size (n₂) = 50

Given proportion of the second sample p₂⁻ = 30/50 = 0.6

Null Hypothesis : H₀: p₁⁻=p₂⁻

Alternative Hypothesis : H₁: p₁⁻≠p₂⁻

Step(ii):-

Z-statistic

$Z = \frac{p_{1} -p_{2} }{\sqrt{pq(\frac{1}{n_{1} } +\frac{1}{n_{2}) } } }$

Where

$P = \frac{n_{1}p_{1} +n_{2} p_{2} }{n_{1} +n_{2} }$

$P = \frac{50X0.2+50X0.6}{50+50} = 0.4$

Z-statistic

$Z = \frac{0.2-0.6}{\sqrt{0.4 X 0.6(\frac{1}{50}+\frac{1}{50} } }$

Z = -4.089

Level of significance =0.10

Z₀.₁₀ = 1.645

|Z| = |-4.089| > 1.645 at 0.10 level of significance

Null hypothesis is rejected at 0.10 level of significance

Final answer:-

There is a difference between the two Population proportions

What is the approximation of 8

Sophie [7]

Answer:

you take the numbers from 1 to 9 in descending order and divide them by the numbers from 1 to 9 in ascending order you get a really good approximation of 8 that is accurate up to eight digit. I also found some other approximations, but their less accurate and interesting.
