How to Find a Critical Z Value LEARNING OBJECTIVE: Calculate a critical z-score for a left-tailed, right-tailed, or two-tailed test. Select the correct statement. a.) The critical z-score for a left-tailed test at a 12% significance level is -0.45. b.) The critical z-score for a right-tailed test at a 9% significance level is 1.34. c.) The critical z-score for a two-sided test at a 4% significance level is 1.75. d.) The critical z-score for a two-sided test at a 20% significance level is 0.85.
Given that the test statistic obtained from a large sample for a two-tailed test is 1.82, what is the p-value for this test? Express your answer accurate to 4 decimal places.
Given the significance level α=0.095 find the following: (a) lower-tailed ?z value z= (b) right-tailed ?z value z= (c) two-tailed ?z value |z|=
Chapter 5, Section 1, Exercise 013 Find the p-value based on a standard normal distribution for each of the following standardized test statistics (a) Z = 0.89 for a right tail test for a difference in two proportions Round your answer to two decimal places p-value0.20 the absolute tolerance is +/-0.01 (b) Z-_2.39 for a left tail test for a difference in two means Round your answer to three decimal places. p-value- the absolute tolerance is +/-0.001 (c) = 2.18...

Calculate a p-value for a left-tailed, right-tailed, or two-sided t-test with a given t-test statistic.The average age of lows residents is 37 years. Amy believes that the average age in her hometown in lowa is not equal to this average and decided to sample 30 citizens in her neighborhood. Using the alternative hypothesis that u=531, Amy found a t-test statistic of 1.311. What is the p-value of the test statistic? Answer choices are rounded to the hundredths place. a.) 0.20 b.) 0.10 c.) 0.07 ...
