A physical education teacher wanted to know the effects of various activity levels on body composition. She surveyed her physical education classes and categorized 30 students into five activity levels based on the amount of daily exercise in which the students participated: inactive, semiactive, normal, active, and very active. She measured percent body fat values using skinfold calipers on all subjects with the following results.
Inactive Semiactive Normal Active Very Active
30.2 29.4 22.9 17.6 10.9
29.6 17.6 25.4 13.4 13.7
35.2 26.4 19.6 20.3 12.8
19.1 25.3 18.7 19.6 14.7
26.3 22.5 21.8 15.1 9.3
22.4 28.6 24.9 10.7 12.7
Required:
a. What is the independent variable in this study? What is the dependent variable?
b. What are the means and standard deviations for each group?
c. Does a significant difference exist among any of the groups?
Answers
Answer:
a. The independent variable is the activity level
The dependent variable is the body composition (the percentage of body fat in the values)
b. The mean and standard deviation are;
(Mean, Standard deviation)
Inactive(27.13, 5.8), Semiactive(24.97, 4.367), Normal(22.217, 2.73), Active(16.12, 3.73), Very Active (12.35, 1.95)
c. Yes
Between Semiactive and Active, Semiactive and Very Active, Normal and Very Active, Normal and Active, Active and Inactive, and Inactive and Very Active
Step-by-step explanation:
a. The independent variable is the activity level
The dependent variable is the body composition (the percentage of body fat in the values)
b. The given data are presented as follows;

[tex]t=\dfrac{(\bar{x}_{1}-\bar{x}_{2}) }{\sqrt{\dfrac{s_{1}^{2} }{n_{1}}-\dfrac{s _{2}^{2}}{n_{2}}}}[/tex]
The degrees of freedom = n - 1 = 6 - 1 = 5
The critical t = 2.5706
Therefore, we have;
The test statistic for Inactive and semi active ≈ 0.72875
The test statistic for Semiactive Normal ≈ 1.309
The test statistic for Inactive and Normal ≈ 1.8773
The test statistic for Semiactive and Active ≈ 3.775 (Significant)
The test statistic for Semiactive and Very Active ≈ 6.464 (Significant)
The test statistic for Normal and Very Active ≈ 7.204 (Significant)
The test statistic for Normal and Active ≈ 3.231 (Significant)
The test statistic for Active and Inactive ≈ 3.91 (Significant)
The test statistic for Active and Very Active ≈ 2.194
The test statistic for Inactive and Very Active ≈ 5.92 (Significant)
Where the test statistic is larger than the critical 't' the statistic is significant
Monica and jaimy are creating number patterns. Monica uses the rule . "Multiply by 3 and stats at 4 .Jaimy uses the rule "add 6 and stars at 12 .which term in Jaimy's
Answers
Answer:
Jaimy's fifth term equals Monica third term of 36.
Step-by-step explanation:
Monica:
Multiply by 3 and starts at 4.
4*3 = 12
12*3 = 36
36*3 = 108
...
So: {3,12,36,108,...}
Jaimy:
Adds 6 and starts at 12. So
12 + 6 = 18
18 + 6 = 24
24 + 6 = 30
30 + 6 = 36
...
So: {12,18,24,30,36,...}
So Jaimy's fifth term equals Monica third term of 36.

x=45
Step-by-step explanation:
This is a triangle so it interior degrees will add up to 180.
W
Since Line AC is tangent to Circle O at point c, Point C measures 90 degrees.
We can find OAC by using the triangle interior theorem,
[tex]45 + 90 + x = 180[/tex]
[tex]135 + x = 180[/tex]

What are the coordinates of the midpoint between the points (-1,4) and (2,-5)
Answers
Answer:
(1/2, -1/2)
Step-by-step explanation:
To find a midpoint add the two x's and divide by 2 so -1+2 / 2 = 1/2
add the two y's and divide by 2 so 4-5 / 2 = -1/2
Put the two numbers together as a coordinate (1/2, -1/2)

2 minutes 10 seconds-------130 seconds put the sign
Answers
Answer:
2 minutes 10 seconds = 130 seconds
Step-by-step explanation:
Given that,
LHS = 2 minutes 10 seconds
RHS = 130 seconds
Solving LHS first,
We know that,
1 minute = 60 seconds
2 minute = 120 seconds
2 minutes 10 seconds = 120s + 10 s
= 130 seconds
It means,
LHS = RHS
So,
2 minutes 10 seconds = 130 seconds
