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:
this means that lot 1 would have more cars. there were 3 cars in lot 1 and 2 in lot 2
Step-by-step explanation:

3:4 2:3
if both have 12 trucks, you need to multiply the number of cars with the number you used to make the trucks 12
3:4 would turn into 9:12
2:3 would be 8:12
this means that lot 1 would have more cars. there were 3 cars in lot 1 and 2 in lot 2
