Imagine I ran a one-way repeated-measures ANOVA with five levels on the independent variable. The results revealed a Greenhouse-Geisser estimate, symbol = .977, and the Huynh-Feldt estimate, symbol = .999. What do these values tells us about the assumption of sphericity? (Hint: When the data are perfectly spherical, these estimates will be 1.) The assumption of sphericity is likely to have been met. The assumption of sphericity is likely to have been violated. We cannot tell anything about the assumption of sphericity from these values. We do not need to check the assumption of sphericity for a one-way repeated-measures ANOVA.

Atest of sobriety involves measuring the subject's motor skills. a sample of 31 randomly selected sober subjects take the test and produce a mean score of 64.4 with a standard deviation of 2. a claim is made that the true mean score for all sober subjects is equal to 65. for each part below, enter only a numeric value in the answer box. for example, do not type "z =" or "t =" before your answers. round each of your answers to 3 places after the decimal point. (a) calculate the value of the test statistic used in this test. test statistic's value = (b) use your calculator to find the p-value of this test. p-value = (c) use your calculator to find the critical value(s) used to test this claim at the 0.2 significance level. if there are two critical values, then list them both with a comma between them. critical value(s) =
