Complete Question

The number of successes and the sample size for a simple random sample from a population are given below. x-4, n 200, [tex]H_o[/tex]: p- 0.01, Ha p>0.01, a 0.05 . determine the sample proportion of x

Answer:

The sample proportion of x is  [tex]\^ p = 0.02[/tex]

Step-by-step explanation:

From the question we are told that

    The number of success is  x = 4

    The sample size is  n  =  200

    The null hypothesis is [tex]H_o : p = 0.01[/tex]

     The alternative hypothesis is  [tex]H_a : p > 0.01[/tex]

      The level of significance is  [tex]\alpha = 0.05[/tex]

Generally the sample proportion of x is mathematically represented as

      [tex]\^ p = \frac{x}{n}[/tex]

=>   [tex]\^ p = \frac{4}{200}[/tex]

=>   [tex]\^ p = 0.02[/tex]
