Using the Central Limit Theorem, it is found that the sampling distribution of the sample proportion of the 50 questions on which you get the correct is approximately normal, with mean of 0.7 and standard error of 0.0648.
<h3>What does the Central Limit Theorem state?</h3>
It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean 
and standard deviation 
, as long as 
and 
.
In this problem, we have that p = 0.7, n = 50, hence the mean and the standard deviation are given as follows:

Well she would need about 11.5 gallons of gas times 1.89 is $21.73 hope this helps
So basically... you divide the 3 to 2 and that's how you get the decimal. The decimal is... 0.666666666667
Answer:
Step-by-step explanation:
4/20 + 11/20 = 15/20
15/20 = 3/4 or 0.75
Answer:
Step-by-step explanation:
Let x be the number of flowers. If Group A were to make x flowers alone, it would take them 10 hours to complete the task, then they make 
flowers in an hour. If Group B were to make x flowers alone, it would take them 15 hours to complete the task, then they make 
flowers in an hour.
The groups decided to work together. They can make 
together in an hour and it takes them 
hours. Group B took a break for 1 hour and 40 minutes (
hour), then Group B works
hours.
Thus,
