Answer:
The true statement about Kendra's sample is:
b) Kendra's samples are precise but not accurate.
Step-by-step explanation:
a) Data and Calculations:
Average age of dogs currently alive = 4.8 years
Average ages of dogs in Kendra's sample
Week Average Age (in years)
1 3.7
2 3.8
3 4.2
4 4.1
5 3.9
6 3.9
7 4.0
Total 27.6
Mean = 3.9 (27.6/7)
b) Accuracy refers to how close Kendra's sample mean age of dogs is to the average age value as stated in the Modern Dog Magazine. While the Magazine stated an average age of 4.8 years, Kendra's sample produced a mean of 3.9 years. On the other hand, precision refers to how close Kendra's sample measurements are to each other. With a mean of 3.9 years, the sample measurements are very close to each other. Therefore, we can conclude that "Kendra's samples are precise but not accurate."

Answer:
See Explanation
Step-by-step explanation:
Given

Solving (a): What does h represents
From the instruction in the question, we understand Cycle city charges an additional 0.75 per hour.
This implies that h represents the additional hour of rentals
Solving (b): What does 15 represents
From the instruction in the question, we understand Cycle city charges an a base charge of $15
This implies that 15 represents the base charge
Solving (c): 0.75h
Referring back to (a) where h represents the additional hour of rentals
0.75h represents the total charges for the additional hour
