Consider a hypothesis testing situation in which the null hypothesis is p = 0.05 and the alternative is p > 0.5. Data is gathered from a random sample and a test statistic of 2.1 is computed. This means the p-value would have to be:
A. less than 0.01.
B. between 0.01 and 0.05
C. between 0.05 and 0.10
D. greater than 0.10
E. More information is needed in order to determine the p-value.

The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject H when the level of significance is (a) a= 0.01, (b) a 0.05, and (c) a0.10. P 0.0749 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? O A. Reject H because the P-value, 0.0749, is greater than a=0.01 O B. Fail to reject Ho because the P-value, 0.0749, is less than a = 0.01 O C. Reject...

Consider a multinomial experiment with n = 260 and k = 4. The null hypothesis to be tested is H0: p1 = p2 = p3 = p4 = 0.25. The observed frequencies resulting from the experiment are: (You may find it useful to reference the appropriate table: chi-square table or F table) Category 1 2 3 4 Frequency 73 44 75 68 a. Choose the appropriate alternative hypothesis. All population proportions differ from 0.25. Not all population proportions are equal...

Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. A test of sobriety involves measuring the subject's motor skills. A study of n = 20 randomly selected sober subjects take the test and produce a mean score of X = 41.0, and we know that o = 3.7. At the 0.01 level of significance, test the claim that the true mean score for all sober subjects is...

5 In a hypothesis test for a proportion, the null hypothesis is HO: p = 0.7 and the alternative hypothesis is H1: P = 0.7 with a = 0.05. Then we reject HO if the test statistic Z is 15 (5 Points) between -1.64 and 1.64 and cannot reject H0 otherwise greater than 1.64 or less than-1.64 and cannot reject H0 otherwise between -1.96 and 1.96 and cannot reject HO otherwise greater than 1.96 or less than-1.96 and cannot reject...

Suppose a hypothesis test is conducted using a significance or alpha level of 0.05, and the null hypothesis is rejected. This means that? A we would also reject the null hypothesis if the significance level had been 0.10 instead of 0.05. B the p-value was greater than 0.05. C we would also reject the null hypothesis if the significance level had been 0.01 instead of 0.05. D All answer options are correct.

Please follow the steps of hypothesis testing, including
identifying the alternative and null hypothesis, calculating the
test statistic, finding the p-value, and making a conclusions about
the null hypothesis and a final conclusion that addresses the
original claim. Use a significance level of 0.10. Is the conclusion
affected by whether the significance level is 0.10 or 0.01?
