2 1/2 = (2*2+1)/2 = 5/2
5/2 : 1/4 = 5/2 * 4/1 = 20/2 = 10
To arrange numbers from least to greatest:
First write them down in decimal form. Now it will be easy to determine which value is greater than the other.
Arrange the decimal numbers from least to greatest.
Finally revert the decimal values to their fraction form having arranged them from one with least value to one with greatest value.
Answer:
The sample observations are not a randomsample, so a test about a population proportion using the normal approximating method cannot be used.
Step-by-step explanation:
The necessary conditions are
The sample must be random and independently selected from the normally distributed population.
n*p and n*q both must be greater than 5
There must be two outcomes "success" and "failure"
The number of trials must be fixed.
From the given information 2), 3)and 4) conditions are satisfied, but not 1) because we are not given that people are selected randomly.
Answer: The sample observations are not a randomsample, so a test about a population proportion using the normal approximating method cannot be used.
