The total number of people that will be selected is 14.
<u>Step-by-step explanation:</u>
For stratified random sampling at first we need to divide the population into some strata and then choose sample from each. For the given problem the response category is
Sample size of strata = (Size of entire sample by populaion size) multiply strata size
= (20 by 300) multiply 210
after solving we get, 14
therefore, 14 people will be selected.
One merit is that here since we divide the whole data into stratas and then select samples from that so it can be used as a guard against unwanted samples and also gives more accurate sample measure. Here since we required samples from the population who gave yes and no opinion so it is better to use stratified sampling method otherwise if we use simple random sampling then we may choose those samples who gave no opinion. But since we don't use that method so we can avoid this.
The df value for the t statistic for this study is 12.
To calculate the df value or degree of freedom we have to learn about test-statistic.
<h3>What is t statistics and how is it related to df(degree of freedom)?</h3>
In the field of statistics , T-statistic is the ratio of the estimated value of the perimeter to its standard error. Degree of freedom or df value denotes the number of data (from a sample) is used to calculate the estimate .
Importantly the degree of freedom is different from the sample space of an experiment.
The formula for calculating the df of a function is given by
df=N1+N2-2
So in the given question, N1=6 and N2=8
Substituting the values we get df=N1+N2-2=8+6-2=12 .
Therefore the value of the degree of freedom is 12.

Answer:
it's hypotenuse
then
base^2+length ^2=hypotenuse^2
5^2+9^2=106^2
11236
if wrong correct me pls
have a great day ahead

So we multiply 2 by 12, and get 24.
Then we multiply 8 by 3, and get 24.
Next we give both terms new denominators -- 3 × 12 = 36.
So now our fractions look like this:
<span><span>24/36</span>−<span>24/36</span></span><span><span>Since our denominators match, we can subtract the numerators.24 − 24 = 0So the answer is:<span>0/36 z</span></span><span>ero divided by anything is just zero. So that's the final answer:
<span>0</span></span></span>
Answer:
x=3z+y/2
i hope this answers your question
