What is the mean absolute deviation? Round to the nearest tenth.
Answer:
The mean absolute value is 7.7, when rounded to the nearest tenth.
Step-by-step explanation:
1.) To get the mean absolute deviation you have to find the mean first:
2.) Then, you have to find the difference of each element in your data set that is away from the mean. Then, you have to find the absolute values of the answers:
3.) Then, you have to find the mean of the absolute values:
Answer:
its 7.7

Answer:
Step-by-step explanation:
The correct answer is d. the chi-squaretest compares the difference between expected and observed frequency counts.
The chi-square test is a statistical test used to analyze the distribution of categorical data. It compares the observed frequency counts of a categorical variable with the expected frequency counts.
The expected frequency counts are calculated based on a null hypothesis, which assumes that there is no significant difference between the observed and expected frequencies.
The test statistic for the chi-square test is calculated as the sum of the squared differences between the observed and expected frequency counts, divided by the expected frequency counts.
The resulting value is compared to a chi-square distribution with a certain number of degrees of freedom to determine the p-value and assess the significance of the observed difference.
Therefore, options a, b, and c are incorrect because they describe other types of statistical tests that are used to compare means or variances between groups, while the chi-square test is specifically designed for analyzing categorical data.

Answer: Relationship between the number of reports and the cost of reports printed is given by
Step-by-step explanation:
Let the number of reports be x
Let the cost of report printed be y
Since we have given that for 50 reports he is paid $32
and for 100 reports printed he is paid $57.
So we have (50,32) and (100,57)
To get the relationship between the number of reports x, and the cost y , we find the slope using two points mentioned above.
As we know the formula for two point slope form :
Now, using the equation of line using two point slope form:
∴ This is the required relationship between the number of reports and the cost of reports printed.
