A famous basketball player scored 97 points in a high scool game, breaking a national record. She made 43 more 2-point baskets t

ziro4ka [17]

X - 3pt baskets (he reaches 3x points)
y - 2pt baskets (he reaches 2y points)

We know, that y=x+43

97 - 1 free throw = 97 - 1 = 96
Sum of points: 96

3x + 2y = 96. Substitute to "y" an expression "x+43" :

3x + 2(x+43)=96
3x+2x+86=96
5x=10 |:5
x=2

So y=x+43=2+43=45

He has made 2 three points baskets and 45 two points baskets

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
