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

The Lakeside Legends, a broomball team, joined a 16-team league. They played each of their 15 opponents 3 times. Every broomball

blondinia [14]

Answer: 90

Step-by-step explanation:

if you multiply the number of times the house played each opponent

Since They played each of their 15 opponents 3 times (keyword 3 Times so you don’t get confused again)

It would be 15x3=45 this answer “45” is the amount of games they played

Now you times it by 2

45x2= 90

Aram says that the least common multiple of 4 and 6 is 24. Which is true about Aram's statement?

mojhsa [17]

Answer:

a. 24 is a common multiple, but not the least common multiple

Step-by-step explanation:

To check which statement is true, we need to follow the steps below;

First, lets find the multiples of 4 and then multiples of 6

Multiples of 4 = 4, 8, 12, 16, 20, 24, 28.....................................................

Multiples of 6 =6, 12, 18, 24, 32 ................................................................

Common multiples of 4 and 6 are 12, 24

The least common multiples of 4 and 6 is 12

Therefore 24 is a common multiple of 4 and 6 but its not the least common multiple of 4 and 6 rather 12 is the least common multiple of 4 and 6.

Next lets find the factors of 4 and 6

Factors of 4 = 1, 2, 4

Factors of 6 = 1, 2, 3, 6.

Common factors of 4 and 6= 1, 2

Greatest common factor of 4 and 6 = 2

Therefore, 24 is also not the greatest common factors of 4 and 6 but rather 2 is the greatest common factor.

Therefore the only true statements of Aram is option a. 24 is a common multiple, but not the least common multiple
