Answer:
Lowest is 100
Highest is 125
Step-by-step explanation:
We use the 5 number summary to be the foundation of a graphical representation referred to as the box plot. One box would move from one quartile which is the lowest quartile Q1 to the another quartile Q3 which is the upper quartile.
Now if a box plot is to be made given the the information in this question, the box is going to go from Quartile 1 to Quartile 3.
Then the Lowest value would be 100 and the highest 125
Answer:
x=1.875 y=-0.875
Step-by-step explanation:
10x-3y=3 10x-3y=3
3(2x+y)=(9)3 +<u>6x+3y=27</u>
1/16(16x)=(30)1/16 = x=1.875
10x-3y=3 10x-3y=3
-5(2x+y)=(9)-5 -<u>10x-5y=4 </u>
1/-8(-8y)=(7)1/-8 = y=-0.875
Answer:
She waited five minutes.
Step-by-step explanation:
You can tell that she waited five mins because between points D and E there is a straight line meaning that she was not moving. So you know that she was standing still waiting.
I hope this helps!!!
Answer: (B)
Step-by-step explanation:
An independent sample test compares two sample means in order to determine the statistical significance of the difference between their population means.
The independent sample test would be the best hypothesis test for this study because:
1. There was a random samples of data from the population
2. There was no relationship between the subjects in each sample. That is;
- subjects in the first group were not also in the second group
- subjects in the first group did not influence subjects in the second group and vice versa.
3. There was independence of observations in this study. Each subject in each group was separately observed and each subject has a given fitness performance score.
4. There are values on both the dependent and independent variables.
- the dependent variable is FITNESS PERFORMANCE and for each subject, it is dependent on either the OLD EXERCISE PROGRAM or the NEW EXERCISE PROGRAM.
5. Our dependent variable her is a continuous variable as we see from the range of fitness scores. The lowest score is 19 and the highest score is 73. This shows that the variable is continuous. All the other scores fall in between.
6. Our independent variable is a categorical variable. Categorized into OLD EXERCISE PROGRAM and NEW EXERCISE PROGRAM.
