Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the population proportion p at the given level of significance using the given sample statistics. Claim: p>0.12; α=0.05; Sample statistics: Modifying above p with caret equals 0.08, n is equal to 250

There is no sufficient evidence to support the claim

Step-by-step explanation:

From the question we are told that

     The level of significance is  

     The  sample proportion is  

     The  sample size is  

Generally for normal sampling distribution can  be used

So  

Since  

      then  normal sampling distribution can  be used

The null hypothesis is  

  The alternative hypothesis is  

The  test statistic is evaluated as

substituting values

The  p-value is obtained from the z  table and the value is

Since the

    Then we fail to reject the null hypothesis

Hence it means there is no sufficient evidence to support the claim
