Answer:
The correct option is B.
Step-by-step explanation:
The given graph represents the sales of sweaters and gloves at her store for the past ten winter weeks.
If the scatter points lie near to a straight line and the slope of the line is positive, then there is a strong positive linear correlation between two variables.
r=1 means strong positive correlation.
r=0 means no correlation.
r=-1 means strong negative correlation.
From the figure it is clear that the scatter points lie near to a straight line and the slope of the line is positive. So, there is a positive linear correlation between the sales of sweaters and gloves.
Therefore the correct option is B.

Answer:
A summary of the data is as follows;
1. Maximum = 34
2. Minimum = 24
3. The 1st quartile is 27
4. The median is or the 2nd quartile 34
5. The 3rd quartile is 33
The data is summarized in the attached box plot
Step-by-step explanation:
24, 25, 29, 30, 31, 31, 32, 34, 34
From the given data, we have the five values of a box and whisker plot as follows;
1. Maximum = 34
2. Minimum = 24
3. The 1st quartile is the term or 27
4. The median (2nd quartile) is the term or 34
5. The 3rd quartile is the term or 33
Hence the attached box plot summarizes the data.
Answer:
0.0158 = 1.58% probability that all of them are under 18.
Step-by-step explanation:
Probability of independent events:
If three events, A, B and C are independent, the probability of all happening is the multiplication of the probabilities of each happening, that is:
The percentage of people under the age of 18 was 23.5% in New York City, 25.8% in Chicago, and 26% in Los Angeles.
This means that
If one person is selected from each city, what is the probability that all of them are under 18?
Since the three people are independent:
0.0158 = 1.58% probability that all of them are under 18.
