The z-statistic for a one-sided test is z=2.29 this test is  A) not statistically significant at either a=0.05 or a=0.01  B) statistically significant at a= 0.05 but not at a=0.01  C) statistically significant at both a=0.05 and a=0.01

Is the type of area that a person lives in a factor in the age that a person experiences their first passionate kiss? The table below shows data that was collected.

Use a level of significance of α=0.1α=0.1.H0: μ1=μ2=μ3H0: μ1=μ2=μ3 H1:H1: At least two of the means differ from each other. For this study, we should use ANOVA The test-statistic for this data = (Please show your answer to 3 decimal places.) The p-value for this sample = (Please show your answer to 4 decimal places.)

The test statistic of z = 1.98 is obtained when testing the claim that p ≠ 0.752. a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the P-value. c. Using a significance level of a = 0.10, should we reject Ho or should we fail to reject Ho?

You are conducting a study to see if the accuracy rate for fingerprint identification is significantly different from 0.51. Thus you are performing a two-tailed test. Your sample data produce the test statistic - 2.153. Find the p-value accurate to Z = - 4 decimal places. p-value

For a sample, a score that is 12 points above the mean has a z-score of z = 1.20. What is the sample standard deviation?

There (is/is not) enough evidence at the ___% level of significance to (support/ Reject) the claim that the mean annual salary for senior level product engineers is

Does color enhance creativity? Test the indicated claim about the standard deviations or variances  of two populations. Subjects are given a creativity exercise on a computer with either a red background or a blue background. The scores are shown in the table. At the 0.05 significance level, test the claim that those tested with red background have creativity scores with a standard deviation equal to the standard deviation for those tested with a blue background.
