as it is two tailed test.
a.)P-value=P(|z|<0.50)
=2*P(Z<-0.5)
=2*0.3085
(use z table)
=0.617
b.)
b.)P-value=P(|z|<1)
=2*P(Z<-1)
=2*0.1587
(use z table)
=0.3174
c.)
P-value=P(|z|<2)
=2*P(Z<-2)
=2*0.0227
(use z table)
=0.0454
d.)
P-value=P(|z|<3)
=2*P(Z<-3)
=2*0.0013
(use z table)
=0.0026
Ans: d.) Z0=3.00

Using a two-tailed one-sample z-test from a sample of size n, a researcher rejects the null hypothesis as z = 2.0 is greater than the critical value 1.96 at α = .05. What does this mean? Choose ALL the correct options from the following. a. As α = .05, the probability that the null hypothesis is correct is less than 5% b. As α = .05, the probability that the alternative / research hypothesis is correct is more than 95%...

Multiple Choice: Question #1 A two tailed hypothesis test is being used to evaluate a treatment effect with ( a = .05). if the sample data produce a Z-score of ( z= -2.24), what is the correct decision? A. Reject the null hypothesis and conclude that the treatment has no effect B. Reject the null hypothesis and conclude that the treatment has an effect C. Fail to reject the null Hypothesis and conclude that the treatment has no effect D....

Write the null and alternative hypotheses. Determine whether the hypothesis test is left -tailed, right- tailed, or two-tailed and the parameter that is being tested. The standard deviation of the average repair bill is generally $35. A researcher believes it is greater than that now. a. Null Hypothesis: b. Alternative Hypothesis: c. Parameter: d. Type of test:

Write the null and alternative hypotheses. Determine whether the hypothesis test is left -tailed, right-tailed, or two-tailed and the parameter that is being tested. The mean age of lawyers in New York is believed to be 53.4 years. A researcher thinks the average is different now. a. Null Hypothesis: b. Alternative Hypothesis: c. Parameter: d. Type of test:

Question 10 You conduct a hypothesis test using a computer and get the following results: Test of p = 0.7 vs p -/-0.7 Z-value -1.57 p-value 0.1164 The significance level for this test is alpha=0.10, so you decide to fail to reject the null hypothesis. Which of the following statements is true? (Select all that apply) (A) If this test was one-tailed instead of two-tailed, you would still fail to reject the null.

Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. Use either the T Calculator or the Normal Calculator to compute the P-value of the following test statistics. (a) The test statistic in a two-tailed is z = 1.39. Round to four decimal places. (b) Find the P-value for a right-tailed test with n = 27 and test statistic t = 1.502. Round to...
