Answer:
The <u>sample proportion</u>, denoted by ^p, is given by the formula ^p= 
, where x is the number of individuals with a specified characteristic in a sample of n individuals.
Step-by-step explanation:
Sample proportion is used to determine sample mean, sample standard error and test the hypotheses about the population.
<em>sample mean</em> can be stated as p and <em>sample standard error</em> can be found using the equation
where
- p is the sample proportion
And if n×p×(1-p)≥10, then sample is assumed large enough to assume normal distribution and apply statistical test.
Answer:
5.5
Step-by-step explanation:
385 divided by 70=5.5
The correct answer in this case would be A. There is only 1/8th percent chance of the spinner landing on 4.
Answer:
314 flowers
Step-by-step explanation:
In order to find how long the perimeter of the circular garden is, we need to find the circumference of the garden.
The circumference of a circle is radius*2*pi. So, in this case, the circumference would be 200*2*3.14. This equals 1256 inches.
Next, we know that flowers are planted every 4 inches, so all we need to do is to find how many 4-inch segments are in 1256 inches.
1256/4=314
Thus, 314 flowers are needed.
