1. 25% if 1/4, so we want to find 1/4 of 176. Best way to get the result is just divide 176 by 4, so 176:4=44 - its the answer.

2. To get the answer we can use proportion
100% -----------20
90% ---------- x
crossmultiply now
100x=90*20
100x=1800     /:100        divide both sides by 100
x=18 - its the answer

3. Similar problem
24 ---------- x
30 ---------- 100%
crossmultiply now
24*100%=30x 
2400%=30x     /:30 divide both sides by 30
2400%:30=x
80%=x - its the answer

According to a poll taken last year, 45% of the cities' residents get most of their news from the Internet. To conduct a follow-
notsponge [240]

Answer:

The sample size is  n  =419

Step-by-step explanation:

From the question we are told that

    The population proportion is  p = 0.45

     The  margin of error is  E =  0.04

Given that the confidence level is  90%

  Then the level of significance can be mathematically represented as

          \alpha  =  100 -90

          \alpha  =  10\%

         \alpha  = 0.10

Next we obtain the level of significance from the normal distribution table the value is    

             Z_{\frac{\alpha }{2} } =  1.645

   Generally the sample size is mathematically represented as  

        n  = [ \frac{Z_{\frac{\alpha }{2} }}{E} ]^2 *  p(1- p )

substituting values

         n  = [ \frac{1.645 }{0.04} ]^2 *  0.45(1- 0.45 )

        n  =419
