Answer 1

Complete Question

Determine whether the normal sampling distribution can be used. The claim is p < 0.015 and the sample size is n=150

Answer:

Normal sampling distribution can not be used

Step-by-step explanation:

From the question we are told that

    The  null hypothesis is  $H_o : p = 0.015$

     The  alternative hypothesis is    $H_a : p < 0.015$

     

The  sample size is  n= 150

Generally in order to use  normal sampling distribution  

     The value  $np \ge 5$

So  

         $np = 0.015 * 150$

         $np = 2.25$

Given that  $np < 5$   normal sampling distribution  can not be used
