The critical values are 0.622, 0.707, 0.789 and 0.834

<h3>How to determine the critical values?</h3>

The sample size is given as:

n = 8

Calculate the degrees of freedom using

df = n - 2

So, we have:

df = 8 - 2

df = 6

Using the table of values of critical values, we have:

Critical values = 0.622, 0.707, 0.789 and 0.834

By comparing the critical values and the linear correlation coefficient, we can conclude that there is no significant linear correlation.

Luis created the graph below to show the temperature from 8:00 a.m. (8 hours after midnight) until 8:00 p.m.
vagabundo [1.1K]

A slope also known as the gradient of a line is a number. The correct option is A, C, and D.

<h3>What is Slope?</h3>

A slope is also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.

For the given question,

  • The temperature increased until 4:00 p.m.

This can be observed in the graph, as the slope of the graph before 4 pm is positive, it can be concluded that the temperature is increased until 4 pm.

  • The temperature decreased after 6:00 p.m.

This can be observed in the graph, as the slope of the graph after 4 pm is negative, it can be concluded that the temperature is decreasing after 4 pm.

  • The temperature increased more quickly between 12:00 p.m. and 4:00 p.m. than before 12:00 p.m.

This can be probed by calculating the slope of the line between the two points. Therefore, the slope between 8 am to 12 pm will be 1, while the slope from 12 pm to 4 pm will be equal to 4/3.

Hence, the correct option is A, C, and D.
