What do the center, spread, and shape of a data set tell you about the data? 17 points

1 answer:

5 0

The centre is the median of the data, so the middle number. IT can also be the mean which is the average.

The spread tells you about the rang of the data.

The shape describes the different types of graphs you get if you graph the data so it could be symmetric or skewed etc. The different shapes tell you different things. For example, a skewed graph might tell you people prefer a certain option.

A cell phone provider offers a plan that costs $30 per month plus $0.10 per text message sent or received. A comparable plan c

mariarad [96]

300 messages would have to be sent or received in order for the plan to cost same each month.

Step-by-step explanation:

Given,

Cost per month = $30

Per text sent or received charges = $0.10

Let,

x be the number of texts sent or received.

A(x) = 0.10x+30

A comparable plan costs = $60 per month

Text messages are unlimited.

B(x) = 60

For the two plans to cost equal;

A(x) = B(x)

$0.10x+30=60\\0.10x=60-30\\0.10x=30$

Dividing both sides by 0.10

$\frac{0.10x}{0.10}=\frac{30}{0.10}\\x=300$

300 messages would have to be sent or received in order for the plan to cost same each month.

Describe the difference between a probability derived from the analytic view (logical analysis), the Relative Frequency view (sa

oee [108]

Answer:

See the explanation

Step-by-step explanation:

<h2>Analytic View:</h2>

If and event can occur in A number of way and fail in B number of ways, then probability of its occurrence is:

$P(A)= \frac{A}{A+B}$

or probability of its failing is:

$P(B)=\frac{B}{A+B}$

<h3>Example:</h3>

Rolling a number smaller than 3 in a dice.

A= 2 (1,2)

B = 4 (3,4,5,6)

$P(A)= \frac{2}{2+4}=\frac{1}{3}$

<h2>Relative Frequency View:</h2>

Definition of Probability in terms of past performances (data). It can be taken as how often things happens divided by all outcomes.

<h3>Example:</h3>

A batter has 50 safe hits at 200 bats, which makes his batting average $\frac{50}{200}= 0.25$ which is the probability.

<h2>Subjective View:</h2>

When you define a probability due to personel beleif in the likelihood of an outcome. It involve no formal calculations and varies from person to person, depending on their past experience.

<h3>Example:</h3>

A person beleives that probability that the batter will hit safely in the next bat is 0.75
