Answer:

The probability that a customer purchases a black SUV is 0.05.

Step-by-step explanation:

<em>The question is incomplete:</em>

<em>At a certain car dealership, the probability that a customer purchases an SUV is </em><em>0.20</em><em>. Given that a customer purchases an SUV, the probability that it is black is </em><em>0.25</em><em>.</em>

The probability that a customer purchases a black SUV can be calculated as the multiplication of this 2 factors:

The probability of a customer purchasing a SUV: P(SUV).
The probability that it is black, given that he or she purchases a SUV (conditional probabilty): P(B|SUV)

We know then:

$P(SUV)=0.25\\\\P(B | SUV)=0.20$

We can now calculate the probability as:

$P(B\,\&\,SUV)=P(B|SUV)\cdot P(SUV)=0.25\cdot0.20=0.05$

The line plot (shown in the attached image) shows the prices of sunglasses at a department store.

Novosadov [1.4K]

a. Mean is 70.8, median is 70, and mode is 60

b. Mean describes the data best

c. Mean can be a misleading central measure in case of outliers

Calculating Mean, Median and Mode

Mean = Total sum of pries / Total number of sunglasses

Mean = (20 + 20 + 50 + 50 + 50 + 60 + 60 + 60 + 60 + 60 + 60 + 70 + 70 + 70 + 80 + 80 + 80 + 80 + 90 + 90 + 90 + 90 + 100 + 100 + 130) / 25

Mean = 70.8

Median = (n/2 + 1)th term

Here, n is the number of sunglasses.

Median = (25/2 + 1)th term

Median =13th term

Median = 70

Mode = Most occurring data

Mode = 70

Why is mean the best central measure to describe the data?

When your data distribution is continuous and symmetrical, such as when your data are normally distributed, the mean is typically the best measure of central tendency to utilize. Thus, mean describes the average price of the sunglasses here

Mean Being Misleading

In case there are outliers, the mean of the data gets highly affected. Hence, it can be misleading for analyzing average price of the data.
