D1,..,d9 = 0,0,2,2,2,3,4,6,8 //there are 9 values, in ascending order
Q2 (median) = d5 = 2 //value in the middle
Q1 = (d2+d3) / 2 = (0+2)/2 = 1
(Q1 is middle value of d1,d2,d3,d4, but there is no middle element among four elements, that is why arithmetic mean is taken)
Q3 = (d7+d8) / 2 = (4+6)/2 = 5
interquantlie range = IQR = Q3 - Q1 = 5 -1 = 4
answer: 4
Answer:
(a) 
(b) 
(c) Fail to reject 
Step-by-step explanation:
Given




Solving (a): The test statistic
This is calculated as:

So, we have:



--- approximated
Solving (b): Range of p value
First, calculate the degree of freedom (df)



Using:
--- significance level
The p value at:
is:

and the range is:


Solving (c): The conclusion
Compare the p value to the level of significance value
We have:


By comparison:

because:

<em>Hence, the conclusion is: fail to reject </em>

The statement that is true is this one: <span>The equation 3.5|6x – 2| = 3.5 has one solution
hope this helps!</span>
<span>The angle is 90 in total, and you have 30, so the other side would be 60, because 90 - 30 is 60, and half of 60 is 30</span>
