An analysis of variances produces dftotal = 35 and dfwithin = 28. For this analysis, what is dfbetween? Round your answer to the nearest whole number.
An experiment has been conducted for four treatments with eight blocks. Complete the following analysis of variance table.
A newspaper article indicated that 43 percent of cars with black seats are white, 46 percent of cars with black seats are blue, 7 percent of cars with black seats are red, and 4 percent of cars with black seats are black. A test was conducted to investigate whether the color of cars with black seats was consistent with the newspaper article. A random sample of cars of these colors was selected, and the value of the chi-square test statistic was χ2=8.2. Which of the following represents the p–value for the test? P(χ2≥8.2)=0.08 A P(χ2≥8.2)=0.04 B P(χ2≤8.2)=0.96 C P(χ2=8.2)=0.00 D The p-value cannot be calculated because the sample size is not given. E
A study tested the claim that heights of Americans and heights of Austrians have different variances with s=7.48092 cm for Americans and 7.14756 cm for Austrians. The sample sizes are n1= 145 and n2= 157. When using the F test with these data, is it correct to reason that there is no need to check for normalcy because n1 is greater than 30, and n2 is greater than 30?

Anthony says to Eric that he is a stronger student because his average grade for the firstsix quizzes is higher. However, Eric replies that he is more stable because the variance of hisgrades is lower. The actual scores of the two friends (presumably, independent and normallydistributed) are in the table. (a) Is there significant evidence to support Anthony’s claim? State H0 and HA. Testequality of variances and choose a suitable two-sample t-test. Then conduct the testand state conclusions. Use unpooled formula (b) Is there significant evidence to support Eric’s claim? State H0 and HA and conductthe test. Perform a one tailed test to compare the variances. For each test, use the 5% level of significance.
