Answer:

22

Step-by-step explanation:

The median of a data set is found by putting the data set in ascending numerical order and identifying the middle number. If there are an odd number of data values in the data set, the median is a single number. If there are an even number of data values in the data set, the median is the average of the two middle numbers. Sorting the data set for the values entered above we have:

12,   17,   17,   22,   25,   31,   35

Since there is an odd number of data values in this data set, there is only one middle number. With 7 data values, the middle number is the data value at position 4. Therefore, the median is 22.

Identify the correct conclusion. Do not reject the null hypothesis. Report that there insufficient evidence to conclude that tre
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 $\text{reaction are dependent}$.
