How can I divide thirty-three into two groups so the ratio is four to seven?

lana [24]

Look at it this way:

-- Since the two groups have the ratio of 4 to 7, then the first group has 4 parts
and the other group has 7 parts.

-- If the first group has 4 parts and the other group has 7 parts, then they have
11 parts all together.

-- Those 11 parts are all parts of 33. There must be ( 33 / 11 ) = 3 items in each part.

Now you can go back to the groups . . .

-- The first group has 4 parts.
With 3 items in each part, that's (4 x 3) = 12 items.

-- The other group has 7 parts.
With 3 items in each part, that's (7 x 3) = 21 items.

mr_godi [17]

The question is incomplete. The complete question is :

Tests for adverse reactions to a new drug yielded the results given in the table. Drug Placebo headaches No headaches 11 7 91 73 The data will be analyzed to determine if there is sufficient evidence to conclude that an association exists between the treatment (drug or placebo) and the reaction (whether or not headaches were experienced. The results of the test are X2 = 1.798 P-value = .1799. Identify the correct conclusion. O Do not reject the null hypothesis. Report that there insufficient evidence to conclude that treatment and reaction are dependent. O Fail to reject the null hypothesis. Report that there insufficient evidence to conclude that the distribution of headaches is uniform for the drug and placebo. O Reject the null hypothesis. Report that there is sufficient evidence to conclude that treatment and reaction are dependent. O Reject the null hypothesis. Report that there is insufficient evidence to conclude that treatment and reaction are dependent.

Solution :

Given :

Drugs Placebo

Headaches 11 7

No headaches 73 91

The results of the test are :

$X^2=1.798$

The P value is given as = 0.1799

The hypothesis test given for dependent or association between the two variables.

$H_0$ : There is no association between the treatment and the reaction

$H_1$ : There is association between the treatment and the reaction.

If the P value is greater than the alpha value, i.e. when

P value > α (0.05), then we reject the $H_0$ .

Therefore, Do not $\text{reject the null hypothesis}$ . Report that $\text{there insufficient}$ evidence to conclude that $\text{treatment}$ as well as $\text{reaction are dependent}$ .
