The mean, median, standard deviation, and interquartile range for each data set is given below.
<h3>What is the definition of Interquartile Range (IQR)?</h3>
When arranged from lowest to highest, the IQR represents the central 50% of values.
Find the median (middle value) of the lower and higher half of the data to get the interquartile range (IQR).
These are the quartile 1 (Q1) and quartile 3 (Q3) values (Q3). The difference between Q3 and Q1 is the IQR.
<h3>What are the measures of central tendency for Manuels Data?</h3>
Using the statistical tool, the following were arrived at:
- Standard Deviation = 3.13961
- Mean = 8
- Median = 8
- IQR = Q3-Q1 = 10 - 6 = 4
<h3>What are the measures of central tendency for Grethcen's Data?</h3>
Using the statistical tool, the following were arrived at:
- Standard Deviation = 4.68737.
- Mean = 9.6
- Median = 9
- IQR = IQR = Q3-Q1 = 12 - 7 = 5.

1+2+3+4+5=14 divided by 5=2.8 so, A.would be your answer.
Answer:
<h3>11 teams having equal 9 members.</h3><h3>The number of members in a team is 9</h3>
Step-by-step explanation:
Given a club has 54 male members and 45 female members. Also given that the club is having a contest, and there must be are all male and all female in teams competing the contest.
<h3>To find the most members a team ca have :</h3>
Male =54 members and Female =45 members
Total number of members = male members + female members
=54+45
=99
∴ Total number of members=99
∴ The number of members in a team is 9.
From the given problem the teams must all be equal, and each and every member should be on a team.
<h3>Hence 11 teams equals 9 members</h3>
Equation of a line through two points is given by y - y1 = ((y2 - y1)/(x2 - x1))(x - x1)
y - (-1) = ((5 - (-1))/(4 - 2))(x - 2)
y + 1 = ((5 + 1)/2)(x - 2)
y + 1 = 6/2 (x - 2)
y + 1 = 3(x - 2) = 3x - 6
-3x + y = -6 - 1
-3x + y = -7
