Answer:
There appears to be a difference between the pulse rates from samples of adult males and females. The average pulse rate of males is 63.75 while that of females is 75.875.
Coefficient of Variation (male) = 33.44%
Coefficient of variation (female) = 28.35%
Step-by-step explanation:
Mean (male) = 
Mean (female) = 
Standard Deviation (male) = 
Standard Deviation (female) = 
Coefficient of Variation = 
For male, CV =
%
For female, CV =
%
Comparison : Pulse rates of males has more variability than that of females since it has a greater coefficient of variation.
-12.5 because 7pm to 10pm are 3 hours.
Which is 3 times -2.5 and it equals -7.5 plus -5 which is -12.5
Assumed that sides are equal
- 5x-3=3x+1
- 5x-3x=1+3
- 2x=4
- x=2
