In a certain university, 12 out of 250 first year students like to listen to classical music. We want to test if the percentage
Rudik [331]

Answer:

Therefor it is clear that  the percentage of first year student like to listen classical music is less than 10 %

Step-by-step explanation:

Given as ;

The total number of first year students in an university = 250

The number of student who like to listen classical music = 12 out of 250

Let x % of student like to listen classical music

So, x% of 250 = 12

or, \frac{x}{100} × 250 = 12

or, x × 250 = 12 × 100

Or, x = \frac{1200}{250}

∴   x = 4.8

I.e the percentage of first year student like to listen classical music is 4.8%

Now, Again

The 10% of the total number of student is

I.e 10% of 250

or,   \frac{10}{100} × 250

Or ,  \frac{2500}{100}

I.e The 10% of the total number of student = 25

Since 4.8 % of total number of students is 12 and 10% of total number of students is 25

Therefor it is clear that  the percentage of first year student like to listen classical music is less than 10 %  . answer
