Question

P>.9 and it is found the statistic is 1.04 Test the claim with 5% significance level. is the test left right or two tailed and what is the p value

Answer 1

Complete Question

The alternative hypothesis is $H_a : p > 0.9$ and it is found the statistic is 1.04 Test the claim with 5% significance level. is the test left right or two tailed and what is the p value

Answer:

    This a right tailed test

  The p-value is   p-value  = 0.14917

Step-by-step explanation:

From the question we are told that

   The alternative hypothesis is $H_a : p > 0.9$

   The test statistics is  $z = 1.04$

    The level of significance is  $\alpha = 0.05$

Generally this a right tailed test because from the alternative hypothesis p > 0.9 i.e due to the greater than sign signifying that test will be focusing on the right tail of the normal curve

From the z table the area under the normal curve to the right corresponding to 1.04 is  

     P( Z>  1.04 )  = 0.14917

Generally the p-value is mathematically represented as

      p-value  =  P( Z>  1.04 )  = 0.14917
