Answer:
I think the answer is -8+-4=-12
Answer:
27.5
Step-by-step explanation:
First you divide up the shape so there is a square and a triangle. Then you would solve for a square: 5 times 4 and you get 20. Then the triangle which you would do 8-5=3 (so you can get the base) and do 3*5/2= 7.5. Then add the two answers
Answer:
The mean of the sampling distribution for the sample proportion when taking samples of size 500 from this population is equal to 0.248.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes 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 a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean
and standard deviation 
Of the 500 people sampled, 124 said that they would be interested in purchasing season tickets to a Six Flags in Ames.
This means that 
The mean of the sampling distribution for the sample proportion when taking samples of size 500 from this population is equal to
By the Central Limit Theorem, it is equal to the sample proportion of 0.248.
Answer:
7
Step-by-step explanation:
Median is the middle value in a list of values arranged in increasing order.
The values given are :2,8,7,8,6,15,6,8,3
Arrange values in ascending order as: 2,3,6,6,7,8,8,8,15
The middle value is: <u>2,3,6,6</u>,7,<u>8,8,8,15</u>
<u>Median is 7</u>
