Question

The test statistic in a two - tailed test is z = - 1.63. A) 0.0516; fail to reject the null hypothecs B) 0.1032; fail to reject the null hypothesis C) 0.0516; reject the null hypothesis D) 0.9484; fail to reject the null hypothesis Formulae the indicated conclusion in nontechnical terms. Be sure to address the original claim. An entomologist writes an article in a scientific journal which claim that fewer than 3 in ten thousand male fireflies are unable to produce light due to a genetic mutation. Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to reject the null hypothesis side the conclusion in nontechnical terms. A) There is not sufficient evidence to support the claim that the true proportion is less than 3 in ten thousand. B) There is sufficient evidence to support the claim that the true proportion is greater than 3 in ten thousand. C) There is not sufficient evidence to support the claim that the true proportion is greater than 3 in ten thousand. D) There is sufficient evidence to support the claim that the true proportion is less than 3 in ten thousand. Assume that a hypothesis test of the given claim will be conducted. Identity the type I or type II error for the test. A medical researcher claims that 10% of children suffer from certain disorder. Identity the type I error for the test. A) Fail to reject the claim that the percentage of children who suffer from the disorder is equal to 10% when that percentage is actually different from 10%. B) Fail to reject the claim that the percentage of children who suffer from the disorder is equal to 10% when that percentage is actually 10%. C) Reject the claim that the percentage of children who suffer from the disorder is equal to 10% when that percentage is actually 10%. D) Reject the claim that the percentage of children who suffer from the disorder is different from 10% when that percentage really is different from 10%. The principal of a school claims that the percentage of students at his school that come from single - parent homes is 11%. Identify the type II error for the test. A) Reject the claim that the percentage of students that come from single - parent homes is equal to 11% when that percentage is actually less than 11%. B) Reject the claim that the percentage of students that come from single - parent homes is equal to 11% when that percentage is actually 11%. C) Fail to reject the claim that the percentage of students that come from single - parent homes is equal to 11%when that percentage is actually different from 11%. D) Fail to reject the claim that the percentage of students that come from angle - parent homes is equal to 11%when that percentage is actually 11%. the P - value for the indicated hypothesis test. In a sample of 88 children selected randomly from one town, it is found that 8 of them suffer from asthma. Find the P - value for a test of claim that the proportion of all children in the town who suffer from asthma is equal to 11%

Explanation / Answer

Solution9:

null hypothesis:

Ho:p=3/10000

Alternativre hypothesis

H1:p<3/10000

Reject null hypothesis means

accept alternative hypothesis

there is suffucient evidence to support the claim that fewer than 3 in 10000
