2 answers:
Answer:
Gary was more thirsty.
Step-by-step explanation:
Given that On a hot summer day, John drank 5⁄11 of a quart of iced tea; Gary drank 7⁄10 of a quart; and Carter drank 3⁄5 of a quart.
We have to tell which man was the most thirsty.
The man which drank more iced tea was most thirsty
John drank==0.4545 of quart
Gary drank = =0.7 of quart
Carter drank = =0.6 of quart
From above 3 we say that Gary drank more water than other 2. Therefore, Gary was more thirsty.

Answer:
The mean of the sampling distribution of the sample proportions is 0.82 and the standard deviation is 0.0256.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For proportions, the mean is and the standard deviation is
In this problem, we have that:
.
So
The mean of the sampling distribution of the sample proportions is 0.82 and the standard deviation is 0.0256.
