Question

A survey is conducted with a random sample at multiple places in the city as shown to analyze the preference of fruits among the people.
From the population size of 400, estimate the total number of people not preferring apple.

• A. 275
• B. 250
• C. 150
• D. 300

Answer 1

The correct option is D 300

In the given sample,

Here,
Sample size = 50 + 80 + 70 = 200

Number of people who prefer apple = 50
Number of people not preferring apple = 80 + 70
= 150

Percentage of people not preferring apple is:
$=\frac{150}{200}\times 100\%=75\%$

Total population size = 400
Total number of people not prefering apple:
$=\frac{75}{100}\times 400=300$


$\therefore$ Total number of people not preferring apple in the city are 300.
