Dr. Romanoff reported the following in a journal: “F (5, 106) = 10.09, p = .04.”  Should Dr. Romanoff state that there are significant differences among the variable means at a .05 alpha level?

The recommended daily dietary allowance for zinc among males older than age 50 years is 15 mg/day. An article reports the following summary data on intake for a sample of males age 65-74 years: n = 117, x = 12.2, and s = 6.60. Does this data indicate that average daily zinc intake in the population of all males age 65-74 falls below the recommended allowance? (Use a = 0.05.)

An independent-measures study comparing two treatment conditions with n = 6 in each sample produces t = 4.00. What is the value of r2 for this study?

The hypothesis should revolve around one of the variables collected for all subjects. Your results section should describe the general course of one subject’s response from your individual analysis and then evaluate your hypothesis for a specific collective variable.  Please explain this in plain english. I dont understand the instructions. Here is a reference of the subjects.

Are Republicans less likely than Democrats to display the American flag in front of their residence on the Fourth of July? 425 of the 659 Republicans surveyed display the flag on the Fourth of July and 538 of the 784 Democrats surveyed display the flag on the Fourth of July.

The following data were obtained from a repeated-measures study comparing two treatment conditions.     Use a repeated-measures ANOVA with α = .05 to determine whether there are significant mean differences between the two treatments. Calculate η2 as a measure of effect size. State the results as they would appear in a research report.
