The hypothesis shows that we have evidence that the proportion surviving after eating organic is higher.
<h3>How to illustrate the information?</h3>
The following can be deduced from the information:
x1 = 275
x2 = 170
n1 = 500
n2 = 500
The sample proportion will be:
p1 = 275/500 = 0.55
p2 = 170/500 = 0.34
The pooled proportion will be:
= (275 + 170)/(500 + 500)
= 0.44
The test statistic is 6.681. It should be noted that the test statistics is a number that's calculated by a statistical test. It shows how the observed data are far from the null hypothesis.
The p value in this scenario is extremely small. The p value is a measurement used to validate a hypothesis against the observed data. Therefore, we have to reject the null hypothesis.
In this case, the hypothesis shows that we have evidence that the proportion surviving after eating organic is higher.

Answer:
For every 1000 pairs sold, the manufacturer expect to replace 239 pairs for free.
Step-by-step explanation:
Given:
Mean (μ) = 2.2, Standard deviation(S.D) (σ) = 1.7 years and x = 1 (1 year)
Let's find the Z score.
Z = 
Now plug in the given values in the above formula, we get
Z = 
Now we have to use the z-score table.
The z-score for 0.71 is 0.2611
Since it z is negative, so we subtract 0.2611 from 0.5000
0.5000 - 0.2611 = 0.2389
Percentage = 0.2389 × 100 = 23.89%
To find replaces for 1000 pairs, we need to multiply 23.89% by 1000
= 
= 239
The cannot be in decimal, when we round off to the nearest whole, we get
239
Number: 1111
1111/1111=1
1*0= 0
Now put 0 in the tenths place
01

Answer:
PT, VP
Step-by-step explanation:
if p is the center and T V and W are on the circle
the radius goes from the center of the circle to the edge of the circle
then PW PT and PW are radii of the circle
