Select the correct comparison set a set b O A the typical value is greater is set a the spread is greater in set b
salantis [7]

Answer:

(a)

Step-by-step explanation:

Given

See attachment for sets A and B

Required

The true statement about both sets

First, we calculate the typical values (mean) of set A and set B.

This is calculated as:

Mean = \frac{\sum fx}{\sum f}

For A:

A= \frac{0*1+2*1+5*1+6*1+7*1}{1+1+1+1+1}

A= \frac{20}{5}

A =4

For B:

B = \frac{7 * 1 + 8 *1 + 9 * 2 + 10 * 1}{1+1+2+1}

B = \frac{43}{5}

B = 8.6

<em>Here, we can conclude that B has a larger typical value</em>

Next calculate the spread (range) of sets A and B

This is calculated as:

Range = Highest -Least

For A:

A = 7 - 0

A = 7

For B

B=10 - 7

B = 3

<em>Here, we can conclude that A has a larger spread.</em>

<em></em>

<em>Hence, (a) is true</em>

Julie box contains two gold hoop earrings and two silver hoop earrings you randomly choose to errands what is the probability th
vesna_86 [32]

The total number of elements is 2+2=4. Since we have 2 silver earrings, we get

P(two\text{silver earrings)}=\frac{1}{4}+\frac{1}{4}=\frac{2}{4}=\frac{1}{2}

the, the probability to get two silver earrings is 1/2, which is equivalent to 0.5.
