<em>In a study of 100 new cars, 29 are white. Find p and q , where p is the proportion of new cars that are white. </em>
Answer:
p = 0.29 and q = 0.71
Step-by-step explanation:
Given
Total new cars = 100
White new cars = 29
Required
Determine p and q
From the question;
<em>p represents white new cars</em>
Hence;
Note that;
Substitute 29 for p
The proportion of p is calculate by dividing p by the total number of new cars (Same process is done for q)
For proportion of p
For proportion of q
