Answer:
Step-by-step explanation:
To set up this proportion, we know that 16 must correspond with 80% and the x, the number we're looking for must correspond with 100%

This would be the correct proportion, and you could simplify it to equal

Answer:
Null hypothesis: <em>H₀</em>: <em>p</em>₁ = <em>p</em>₂.
Alternate hypothesis: <em>H₀</em>: <em>p</em>₁ ≠ <em>p</em>₂.
Step-by-step explanation:
A statistical experiment is conducted to determine whether the proportions of unemployed and underemployed people who had relationship problems were different.
Let <em>p</em>₁ = the proportion of unemployed people who had relationship problems and <em>p</em>₂ = the proportion of underemployed people who had relationship problems.
A hypothesis test for difference between proportions, can be conducted to determine if there is any difference between the two population proportions.
Use a <em>z</em>-test for the test statistic.
The hypothesis test is:
<em>H₀</em>: There is no difference between the proportions of unemployed and underemployed people who had relationship problems, i.e. <em>p</em>₁ = <em>p</em>₂.
<em>Hₐ</em>: There is a significant difference between the proportions of unemployed and underemployed people who had relationship problems, i.e. <em>p</em>₁ ≠ <em>p</em>₂.
Just addum up.
You should get the sum of 1.981 .
That's in standard form.
Ok so 9(46) means
9*46
So 9*46 would be ur 1st way and ur 2nd would be
46*9
Check:-
9*46=414
46*9=414
Ans
9*46
46*9
