Using it's concept, the probability is given as follows:

P(more than 1 hour of TV | 6th period class) = 0.647 = 64.7%.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem, from the table, we have that there are 11 + 6 = 17 students in 6th period class, of which 11 watched more than 1 hour of TV, hence the probability is given by:

P(more than 1 hour of TV | 6th period class) = 11/17 = 0.647 = 64.7%.

Write an equation that has a graph with the shape of y = x^2, but shifted left 3 units.

$\bf % template detailing

\left. \qquad \right. if\ \frac{{{ C}}}{{{ B}}}\textit{ is negative, to the right}\\\\
\left. \qquad \right. if\ \frac{{{ C}}}{{{ B}}}\textit{ is positive, to the left}\\\\$

$\bf \bullet \textit{ vertical shift by }{{ D}}\\
\left. \qquad \right. if\ {{ D}}\textit{ is negative, downwards}\\\\
\left. \qquad \right. if\ {{ D}}\textit{ is positive, upwards}\\\\
\bullet \textit{ period of }\frac{2\pi }{{{ B}}}$

now, with that template in mind, let's see

$\bf y=x^2\implies 
\begin{array}{llll}
y=(&1x&-0)^2\\
&B&C
\end{array}$

so, just change C to +3, thus C/B is 3/1

Answer:

Sample 1 mean: 6.375

Sample 2 mean: 6.375

Sample 3 mean: 6.625

Range of sample means: 0.25

The first and last boxes should be checked, as they are true.

Step-by-step explanation:

To calculate the mean you must add all of the numbers together and then divide the sum by the quantity of numbers. Ex: 3+7+8+3+7+9+6+8 = 51.

51/8 = 6.375.
