Roll the number cube to find the observed frequency. Which statements are true? Check all that apply

Answer:

(a) and (c)

Step-by-step explanation:

Given

See attachment for complete question

Required

Select all true statements

First, calculate the total observed frequency;

[tex]Total = 11 + 16 + 14 + 20 + 12 + 17[/tex]

[tex]Total = 90[/tex]

(a): Relative frequency of 4 is 2/9

Relative frequency is calculated by:

[tex]RF= \frac{Observed\ Frequency}{Total}[/tex]

For roll 4

[tex]Observed\ frequency = 20[/tex]

So, the relative frequency is:

[tex]RF = \frac{20}{90}[/tex]

Simplify

[tex]RF = \frac{2}{9}[/tex]

(a) is true

(b): Experimental probability of 3 greater than its theoretical probability

The experimental probability is its relative frequency;

For roll 3

[tex]Observed\ frequency = 14[/tex]

The experimental probability is:

[tex]Pr = \frac{14}{90}[/tex]

Simplify

[tex]Pr = \frac{7}{45} = 0.156[/tex]

To calculate  the theoretical probability, w have:

[tex]S = \{1,2,3,4,5,6\}[/tex] ---- sample space

[tex]n(S)= 6[/tex]

[tex]n(3) = 1[/tex] --- number of times 3 occur

The theoretical probability is:

[tex]Pr = \frac{1}{6} = 0.167[/tex]

The theoretical probability is [tex]greater\ than\ the[/tex] experimental probability.

(b) is false

(c): Experimental probability of 2 greater than its theoretical probability

Using the explanations in (b), we have:

For roll 2

[tex]Observed\ frequency = 16[/tex]

The experimental probability is:

[tex]Pr = \frac{16}{90}[/tex]

Simplify

[tex]Pr = \frac{8}{45} = 0.178[/tex]

To calculate the theoretical probability, we have:

[tex]n(S)= 6[/tex]

[tex]n(2) = 1[/tex]

The theoretical probability is:

[tex]Pr = \frac{1}{6} = 0.167[/tex]

The experimental probability is [tex]greater\ than\ the[/tex] theoretical probability.

(c) is true

(d): Relative frequency of 5 is 2/13

For roll 5

[tex]Observed\ frequency = 12[/tex]

The relative frequency is:

[tex]RF = \frac{12}{90}[/tex]

Simplify

[tex]RF = \frac{2}{15}[/tex]

(d) is true
