He is not correct because when you multiply 30 by 3 1/3 you get 100, 24x 3 1/3= 80, not 70.
Hope this helps :)
Answer:
The critical values of r are -0.708 and 0.708.
Step-by-step explanation:
A statistical test is being performed to determine whether there is any linear correlation between two variables.
The hypothesis can be defined as follows:
<em>H</em>₀: There is no linear correlation between two variables, i.e. <em>ρ</em> = 0.
<em>H</em>ₐ: There is a significant linear correlation between two variables, i.e. <em>ρ</em> ≠ 0.
The test statistic is given as follows:

The degrees of freedom of the test is:

The significance level of the test is, <em>α</em> = 0.01.
The critical values of <em>r</em> are:

*Use the <em>r</em> critical value table.
Thus, the critical values of r are -0.708 and 0.708.

Step-by-step explanation:
8x7=56 \2=28 + x = 36.5
Answer:
D. 125cm
Step-by-step explanation:
Round each number for an estimate so you get 5 x 5 x 5 = 125
you're right option B is the answer to that one
