For a repeated-measures study comparing two treatments with 12 scores in each treatment, what is the df value for the t statisti
marishachu [46]

The degree of freedom for t statistic is 11.

According to the given question.

For a repeated-measure study, comparing two treatments with 12 scores in each treatment .

So, we can say that sample size, n = 12.

We know that, when you have a sample and estimate the mean, we have

n – 1 degrees of freedom, where n is the sample size.

Therefore,

The degree of freedom for the given sample test will be

d.f = n -1

⇒ d.f = 12 - 1

⇒ d.f = 11

Hence, the degree of freedom for t statistic is 11.

By visual inspection determine the best-fitting regression model for the data plot below
Pie

Answer:

Exponential

Step-by-step explanation:

By visual inspection the graph generated by the points plotted is an exponential graph as the graph curves upward. The graph is also continous and differs from either a decreasing or increasing Linear graph, which shows a straight best of fit pattern. Hence, the graph most closely represents an exponential graph from visual examination.

Carl has a rock collection. Of the rocks, 3/8 are quartz and 1/3 are granite. What fraction of Carl's rocks are quartz or granit
hoa [83]

Answer:

\frac{17}{24} <em>of Carl's rocks are quartz or granite</em>

Step-by-step explanation:

<u>Proportions and Fractions </u>

A proportion is expressed as a fraction a/b, where a and b are compared by division. If a=b, the proportion (or ratio) equals 1, if a<b, the ratio is less than 1, and if a>b, the ratio is greater than 1. The proportion of elements of a set to the total number of elements of the set is less than one, and the sum of all them equals 1.

We know 3/8 of Carl's rock collection are quartz and 1/3 are granite. If both subsets of rocks are mutually exclusive or disjoint (cannot happen simultaneously), then the proportion of both is the sum of the fractions.

\displaystyle \frac{3}{8}+\frac{1}{3}=\frac{9+8}{24}=\frac{17}{24}
