Answer:
he has 5 quarters, 4 dimes and 6 nickles
Step-by-step explanation:
you can find this by adding the amount of coins he counted in total (19 coins) and the total amount of coins he had (15), the subtract 15 from 19 which will give you 4, this means that in both times he counted coins, only 4 of those coins in both counts were the same, and if you see, they mention dimes twice in both counts, this means the 4 coins that are shared between both counts are dimes, then dubstract 4 from 9, that's 5 so it's the 5 quarters, and substract 4 from 10 which will give you the 6 nickles
Divide the numerator and denominator by 5 and get 1/12
so 5/60 simplified is 1/12
Hope this helps! :D
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.
