lutik1710 [3]

Answer:

The correct statement is  

The  null hypothesis is  H_o  :  p =  0.18

The alternative hypothesis is  H_a :  p >  0.18

Step-by-step explanation:

From the question we are told that

    The population proportion is  p  =  0.18  

    The  sample size is  n  =  1240 airplane

     The  number of airplane is  k  =  310

 

Generally the sample proportion is  

      \^ p = \frac{k}{n}

=>   \^ p = \frac{310}{1240}

=>   \^ p =0.25

The  null hypothesis is  H_o  :  p =  0.18

The alternative hypothesis is  H_a :  p >  0.18

Given that 4704/m = n^2, where m and n are whole numbers and n is as large as possible, find the value of m and of n
Andrews [41]

Answer:

n=28,m=6

Step-by-step explanation:

Rearrange to give 4704 = m * n^2

Express 4704 in its prime factorisation:

2^5 * 3^1 * 7^2

We know that n must be as large as possible and, because it is squared, be the even numbers.

We get n^2 = 2^4 * 7^2 so n = 2^2*7 = 28

m is the leftovers

2^1*3 = 6
