Part A:
For this one, you have to find the median. So first you would put them in order from least to greatest. After you do that you should get,
TEAM L: 4, 4.8, 9, 9.4, 9.75, 13, 17
TEAM M: 3.2, 6, 6.25, 8, 9.5, 9.7, 14
TEAM N: 1, 4.75, 5.6, 13, 14.5, 19, 20
next go from side to side crossing them out evenly till you get to the number in the center.
TEAM L: 9.4
TEAM M: 8
TEAM N: 13
the question asks which team scores more consistently so that would be the team with the highest marking which is team n
so your answer for part A is TEAM N would be awarded the team with the most consistent scoring
part B: you find the average by finding the mean. To find the mean you must add all the numbers up and then divide by how many numbers there are. First we are going to add them up,
TEAM L: 4+17+13+9.4+9+9.7+4.8 = 66.95
TEAM M: 6+14+8+9.7+9.5+6.25+3.2 = 56.65
TEAM N: 1+20+19+13+14.5+4.75+5.6 = 77.85
lastly since all of them consist of 7 numbers, you will divide all the solutions by 7 giving you,
TEAM L: 9.56 (rounded)
TEAM M: 8.09 (rounded)
TEAM N: 11.12 (rounded)
the question asks which team has the higher average score, therefore TEAM N would be the answer since it consist of the highest number.
so your answer for part B is TEAM N would be awarded the team with the highest average score.
ANSWERS....................
PART A: TEAM N would be awarded the team with the most consistent scoring.
PART B: TEAM N would be awarded the team with the highest average score.
Equivalent because they are the same
Answer:
C. is irrational D. is non existing.
Step-by-step explanation:
C is an infinite number that never repeats which makes it irrational, while there is no answer to D; it doesn't exist.
hope this helps
Answer:
Grades between 62 and 64 result in a D grade.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
Find the numerical limits for a D grade.
D: Scores below the top 84% and above the bottom 10%
So below the 100-84 = 16th percentile and above the 10th percentile.
16th percentile:
This is the value of X when Z has a pvalue of 0.16. So X when Z = -0.995.
10th percentile:
This is the value of X when Z has a pvalue of 0.1. So X when Z = -1.28.
Grades between 62 and 64 result in a D grade.
