Matt was given the problem: "16 is 80% of what?"

irga5000 [103]

Answer:

$\frac{16}{x} = \frac{80}{100}$

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%

$\frac{16}{x} = \frac{80}{100}$

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

$\frac{16*100}{80}$

A USA Today/Gallup poll asked a group of unemployed and underemployed Americans if they have had major problems in their relatio

Answer:

Null hypothesis: H₀: p₁ = p₂.

Alternate hypothesis: H₀: p₁ ≠ p₂.

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 p₁ = the proportion of unemployed people who had relationship problems and p₂ = 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 z-test for the test statistic.

The hypothesis test is:

H₀: There is no difference between the proportions of unemployed and underemployed people who had relationship problems, i.e. p₁ = p₂.

Hₐ: There is a significant difference between the proportions of unemployed and underemployed people who had relationship problems, i.e. p₁ ≠ p₂.
