1) A student randomly and independently samples and assigns 6 participants to one of 4 conditions. She gives each group a treatment she believes will affect performance on the dependent measure. Higher scores indicate better performance. The ANOVA summary table is from the data that she has collected. Find the MSbetween. If needed, please round to two decimal places.

2)
A student randomly and independently samples and assigns 15 participants to one of 6 conditions. She gives each group a treatment she believes will affect performance on the dependent measure. Higher scores indicate better performance. The ANOVA summary table is from the data that she has collected. Find the MSwithin. If needed, please round to two decimal places.

3)
A student randomly and independently samples and assigns 10 participants to one of 5 conditions. She gives each group a treatment she believes will affect performance on the dependent measure. Higher scores indicate better performance. The ANOVA summary table is from the data that she has collected. Find F. If needed, please round to two decimal places.

A researcher is investigating the effects of emotion and gender
on cooperation. He randomly assigns participants to one of three
conditions: control, guilt, happiness
After inducing one of the three emotions, the researcher measures
each participant's level of cooperation in a game, on a scale from
1 to 10.
Men:
Control: 5 4 7 4 3 5 5 6
Guilt: 6 9 7 8 6 7 7 8

An experimenter who is interested in the effects of pharmaceutical
commercials on mood randomly assigns participants to three groups:
a depression medication commercial condition, an anxiety medication
commercial condition, and a faucet commercial condition. After
viewing the commercials, participants report their level of
sadness. Higher scores indicate more sadness. Conduct an analysis
of variance and report the obtained F-ratio below.

Questions 8 – 13. In an experiment examining
humor and memory, a researcher randomly assigns participants to one
of two groups. Half of the participants saw sentences that were
humorous and the other half of participants saw sentences there
were non-humorous. The researcher measures the number of sentences
recalled and hypothesizes that the humorous group will remember
more sentences than the non-humorous group.

Forty-eight participants were randomly assigned to do math tasks
under one of three conditions: 16 while listening to soft gentle
music, 16 while listening to loud intense music, and 16 while in
silence. The means and estimated population variances for the three
groups were: Soft-gentle: M = 33, S2 =
25; Loud-intense: M = 42, S2 = 36;
Silence M = 42, S2 = 16.
Do these results suggest that there is a difference in performance
on this kind of...

A researcher randomly assigns 33 subjects to one of three
groups. Group 1 receives technical dietary information
interactively from an on-line website. Group 2 receives the same
information from a nurse practitioner, while Group 3 receives the
information from a video made by the same nurse practitioner.
The researcher looked at three different ratings of the
presentation: difficulty, usefulness, and importance to determine
if there is a difference in the modes of presentation. In
particular, the researcher is interested in...

1. A statistics student takes a poll five randomly selected
coffee shops, then randomly selects 6 customers from each coffee
shop to find out if they support the President’s decision for
declaring the construction of a southern border wall a national
emergency.

voting population?

Each student arrives in office hours one by one, independently
of each other, at a steady rate. On average, three students come to
a two-hour office hour time block. Let S be the number of students
to arrive in a two-hour office hour time block.
What is the distribution of S? What is its parameter?
Group of answer choices
S ∼ Geo(1/3)
S∼Pois(3)
S∼Bin(2,1/3)
S-Pois(1.5)
What is the probability that S = 4?
What is the probability that S ≤...

Suppose a hypertension trial is mounted and 18 participants are
randomly assigned to one of the comparison treatments. Each
participant takes the assigned medication and their systolic blood
pressure (SBP) is recorded after 6 months on the assigned
treatment. The data are presented in the table below. Compute the
totals for each column (1pt).
Group 1 Standard Treatment : 124 111 133 125 128 115 =
