6.2 = 1.2\pi\sqrt{L(0.0001)}
\frac{6.2}{1.2\pi} = \frac{1.2\pi\sqrt{L(0.0001)}}{1.2\pi}
1.644601079 = \sqrt{L(0.0001)}
(1.644601079)^{2} = (\sqrt{L(0.0001)})^{2}
2.704712708 = L(0.0001)
\frac{2.704712708}{0.0001} = \frac{L(0.0001)}{0.0001}
27047127.08 = L

I had to divide each number by 1.2π, make sure that it can be multiplied by itself twice, and have to divide it by 0.0001 to find out what L is equal to.

You are testing the claim that the proportion of men who own cats is significantly different than the proportion of women who ow
otez555 [7]

Answer:

Step-by-step explanation:

This is a test of 2 population proportions. Let 1 and 2 be the subscript for the men and women who own cats respectively. The population proportion of men and women who own cats would be p1 and p2 respectively.

p1 - p2 = difference in the proportion of men and women who own cats.

The null hypothesis is

H0 : p1 = p2

p1 - p2 = 0

The alternative hypothesis is

Ha : p1 ≠ p2

p1 - p2 ≠ 0

it is a two tailed test

Sample proportion = x/n

Where

x represents number of success

n represents number of samples

For men

n1 = 80

p1 = 55/100 = 0.55

x1 = p1n1 = 0.55 × 80 = 44

For women,

n2 = 100

p2 = 30/100 = 0.3

x2 = p2n2 = 0.3 × 100 = 30

The pooled proportion, pc is

pc = (x1 + x2)/(n1 + n2)

pc = (44 + 30)/(80 + 100) = 0.41

1 - pc = 1 - 0.41 = 0.59

z = (p1 - p2)/√pc(1 - pc)(1/n1 + 1/n2)

z = (0.55 - 0.3)/√(0.41)(0.59)(1/80 + 1/100) = 3.39

Test statistic = 3.39

How do u put 3 6/60 as a decimal?
pochemuha
3 over 1 + 6 over 60

[3 over 1 × 60 over 60] + 6 over 60

180 over 60 + 6 over 60 ➡ 186 over 60

186 over 60 ➡ 31 over 10

Then we divide 31 from 10 which give you the quotient of 3.1..


(((Meaning ➡ '"3.1" would be your answer)))

How can i identify a slope
Nonamiya [84]

Answer:

Rise over Run.

Step-by-step explanation:

If it's on a line on a graph you count how many it goes up until it's aligned with the next point and then you count how ever many over until it hits it. So it could be 2 up and 4 over making the slope 2/4.

I'm sorry that might not make much sense I'm bad at explaining but let me know if that helps at all!!
