Arianna gathered data about the distance of 20 cities from the equator and the average hours of sunlight per day in December for
stich3 [128]

<u>Answer-</u>

<em>A. strong negative correlation.</em>

<u>Solution-</u>

<u>Direction of a relationship</u>

  1. Positive- If one variable increases, the other tends to also increase. If one decreases, the other tends to also. It is represented by positive numbers(i.e 0 to 1).
  2. Negative- If one variable increases, the other tends to decrease, and vice-versa.  It is represented by negative numbers(i.e 0 to -1)

<u>Strength of a relationship</u>

  1. Perfect Relationship- When two variables are linearly related, the correlation coefficient is either 1 or -1. They are said to be perfectly linearly related, either positively or negatively.
  2. No relationship- When two variables have no relationship at all, their correlation is 0.

As in this case, correlation coefficient was found to be -0.91, which is negative and close to -1, so it is a strong negative correlation.

Jaiden ran a 100 yard dash three times and took the average of his times. His times were 12.7, 11.2 and 11.8 seconds. On average
tekilochka [14]

Using the mean concept, it is found that on average, it takes him 11.9 seconds to run a 100 yard dash.

<h3>What is the mean?</h3>

The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.

In this problem, the three observations are given by:

12.7 s, 11.2 s, 11.8 s.

Hence the mean is:

M = (12.7 + 11.2 + 11.8)/3 = 11.9.

On average, it takes him 11.9 seconds to run a 100 yard dash.
