Hatshy [7]

Answer:

There are 221 hot dogs and 169 hamburgers

Step-by-step explanation:

(If you need me to explain a little clearer, please comment so I can edit!)

17 : 13 = 30

x : y = 390

390 ÷ 30 = 13

17 · 13 = x

221 = x

13 · 13 = y

169 = y

Answer:

The sample size is  n = 451

Step-by-step explanation:

From the question we are told that

   The margin of error is  E = 0.03

    The sample proportion is  \^ p = 0.12

From the question we are told the confidence level is  95% , hence the level of significance is    

      \alpha = (100 - 95 ) \%

=>   \alpha = 0.05

Generally from the normal distribution table the critical value  of  \frac{\alpha }{2} is  

   Z_{\frac{\alpha }{2} } =  1.96

Generally the sample size is mathematically represented as  

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

=>   n = [\frac{1.96}{0.03} ]^2 *0.12 (1 - 0.12 )

=>   n = 451
