<h3>Answer:  14 & 4/9  or 14 \frac{4}{9}</h3>

This is a mixed number.

The whole part is 14. The fractional part is 4/9.

=======================================================

Work Shown:

2/3 is the same as 6/9 after you multiply top and bottom by 3

So,

\frac{2}{3} = \frac{6}{9}\\\\\text{ and} \\\\9 \frac{2}{3} = 9\frac{6}{9}

meaning we are wanting to find 9\frac{6}{9}+ 4\frac{7}{9}

Add the fractional portions

6/9 + 7/9 = (6+7)/9 = 13/9

and add the whole number portions as well

9+4 = 13

This means,

9\frac{6}{9}+4\frac{7}{9} = 13\frac{13}{9}

Now let's convert the improper fraction 13/9 into a mixed number and simplify,

13\frac{13}{9} = 13 + \frac{13}{9}\\\\13\frac{13}{9} = 13 + \frac{9+4}{9}\\\\13\frac{13}{9} = 13 + \frac{9}{9}+\frac{4}{9}\\\\13\frac{13}{9} = 13 + 1+\frac{4}{9}\\\\13\frac{13}{9} = 14+\frac{4}{9}\\\\13\frac{13}{9} = 14\frac{4}{9}\\\\

kicyunya [14]

Answer is given below :

Step-by-step explanation:

  • Histograms are used in group frequency parameters. Furthermore, it is useless as a given set of five parameters or data and only results in a bar graph and, basically, the vertical graph mentioned above is the correct choice to display the numbers.
  • It is used to expand on the definition of the histogram when the frequency is grouped. For example, data sets 1–5, 6–10, 11–15 and 16–20 can now be used to describe histograms due to the given number and size of data.

Construct a 96% confidence interval if a sampling distribution has a mean of 20, a standard deviation of 5, and a size of 100.
MAXImum [283]

Using the t-distribution, the 96% confidence interval is given as follows:

(18.96, 21.04).

<h3>What is a t-distribution confidence interval?</h3>

The confidence interval is:

\overline{x} \pm t\frac{s}{\sqrt{n}}

In which:

  • \overline{x} is the sample mean.
  • t is the critical value.
  • n is the sample size.
  • s is the standard deviation for the sample.

The critical value, using a t-distribution calculator, for a two-tailed 96% confidence interval, with 100 - 1 = 99 df, is t = 2.0812.

The parameters are given as follows:

\overline{x} = 20, s = 5, n = 100

Hence the bounds of the interval are:

\overline{x} - t\frac{s}{\sqrt{n}} = 20 - 2.0812\frac{5}{\sqrt{100}} = 18.96

\overline{x} + t\frac{s}{\sqrt{n}} = 20 + 2.0812\frac{5}{\sqrt{100}} = 21.04
