Denise runs a dependent samples t-test and calculates r2subjects=.46 and r2condition=.23. b) If SStotal= 100, what is the SSerror?  c) Which effect size(s) reflects the explained variance due to her experimental manipulation? r2error r2condition both r2subjects and r2condition r2subjects

Explain whether homogeneity of variance is satisfied for this analysis, and be clear on how you decided this.

I'm stuck on D because I'm having a hard time with P-value.

A transect is an archaeological study area that is 1/5 mile wide and 1 mile long. A site in a transect is the location of a significant archaeological find. Let x represent the number of sites per transect. In a section of Chaco Canyon, a large number of transects showed that x has a population variance σ2 = 42.3. In a different section of Chaco Canyon, a random sample of 24 transects gave a sample variance s2 = 50.3 for the number of sites per transect. Use a 5% level of significance to test the claim that the variance in the new section is greater than 42.3. Find a 95% confidence interval for the population variance. (a) What is the level of significance? (b) Find the value of the chi-square statistic for the sample. (Round your answer to two decimal places.) (C) Find the requested confidence interval for the population variance. (Round your answers to two decimal places.) Interpret the results in the context of the application.

The crop researcher wants to test the effect of three different fertilizer mixtures on crop yield. An experiment was done for 15 different fields for all three fertilizer mixtures. The crop researcher performed ANOVA test (alpha =0.1) on the data, with the output given below (some metrics are missing and need to be calculated by you).
