The experiment is comparing veterinary and pets, and that pets are more vulnerable to cardiovascular disease than its counterpart.
Hypothesis is a education claim that is based on observation. Moreover, it is tested to check whether it is supported by the reality of the situation or not. Now, the hypothesis for this can be: there is a significant difference between the blood cholesterol levels among dogs and humans and how it affects cardiovascular disease.

Hello there,
There is a total of 40 animals in that in 10 zebras, 10 lions, 10 elephants, and 10 monkeys.
So the probability of them both being lions is pretty rare. 2/40 so that would give you a 1/20 chance of both crackers being both lions.
I hope this helps!
The owner is most likely cheating because it is usually a 50|50 chance of winning. But, you usually only get 50, and win a bit less and loose more. So, he is most likely cheating. (Hope this helped :D)
Answer:
Not necessarily, because this wasn't an experiment.
Step-by-step explanation:
Answer:
0.42 is closest to the proportion of customer purchase amounts between $14.00 and $16.00
Step-by-step explanation:
Mean = 
Standard deviation = 
We are supposed to find the proportion of customer purchase amounts between $14.00 and $16.00
P(14<x<16)
Formula : 
At x = 14
Refer the z table for p value
P(x<14)=0.1922
At x = 16
Refer the z table for p value
P(x<16)=0.6141
P(14<x<16)=P(x<16)-P(x<14)=0.6141-0.1922=0.42
So, Option C is true
Hence 0.42 is closest to the proportion of customer purchase amounts between $14.00 and $16.00
