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

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
