Answer:
And rounded up we have that n=8068
Step-by-step explanation:
The margin of error for the proportion interval is given by this:
(a)
We want for this case a 95% of confidence desired, our significance level would be given by 
and 
. And the critical value would be given by:
The margin of error for this case is 
and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The estimated proportion for this case is 
. And replacing into equation (b) the values from part a we got:
And rounded up we have that n=8068
Answer:
He pays $39.56
Step-by-step explanation:
If finding the discount, always divide the percent by 100.
25% = 0.25
52.75*0.25=13.1875
Because its money, round to hundredths place, $13.19
Subtract the "percent" (13.19) from 52.75
52.75 - 13.19 = $39.56
