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:

Step-by-step explanation:
Answer:
12 hours
Step-by-step explanation:
so what you do is take your $180 money amount and then divide it by your 15 or 12 dollar money amount and you should get your answer also your "answer" for the things you gave us is
15 x + 10 y = 180
Answer:
Choice B & C
Step-by-step explanation:
563 - 192 = 371
The subtraction equals to 371.
100 + 90 + 210 = 400
The answer does not equal to 371 in choice A.
563 - 200 + 8 = 371
The answer equals to 371 in choice B.
571 - 200 = 371.
The answer equals to 371 in choice C.
