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:
70 shirts
Step-by-step explanation:
First off, there are 5 shirts. 2 shirts take 28 seconds. If you divide 28 by 2, that means that each shirt takes 14 seconds.
5x14=70
Therefore, it takes 70 seconds to fold 5 shirts.
Answer:
1. After solving we get value of x: 
2. After solving we get value of x:
Step-by-step explanation:
We need to Solve the equations.
1. 
Step 1: Subtract 5x on both sides
Step 2: Subtract 10 on both sides
Step 3: Divide both sides by -11
So, after solving we get value of x:
2. 
Step 1: Subtract 5x on both sides
Step 2: Subtract 7 on both sides
Step 3: Divide both sides by -11
So, after solving we get value of x:
