A developmental psychologist would like to know whether there is a difference in the sociability scores of children according to the number of siblings they have. He chose three random samples of n = 5 children each according to three groups and measured their level of sociability using a standardized test. The scores are shown in the table below. Do the scores indicate significant differences among the three groups?

a. Using the 5 steps of hypothesis testing, test at α .05. (15 pts)
b. Conduct two post hoc tests, Tukey’s HSD Test and the Scheffe Test, both at α .05, and compare your answers. (9 pts)
Need help with the ten step by hand ANOVA ... specifically the sum of squres/between/within calculations in the hypothesis testing
and the steps associated with the post hoc tests
Thank you!!

You would like to know whether there is a difference between the
rate of cooling of freshly killed corpses versus those that were
reheated (to determine if you could fool a coroner about time of
death). You tested several rats for their cooling constant, both
when the rat was freshly killed and after the same rat was
reheated. Assuming the distribution ofn differences is normal, is
there any difference in the cooling constants between freshly
killed and reheated rats?

A developmental psychologist wanted to know whether watching
videos aimed at increasing the cognitive abilities of toddlers
(e.g., Baby Einstein) really helped. He recruited 30
families from the local community with a child from 18 months to 24
months in the home. Parents in the
experimental group were instructed to have their toddler watch the
video for 10 minutes per day for 4 weeks. Parents
in the control condition spent the same amount of time playing with
their toddlers. The psychologist was also
interested...

A psychologist would like to determine whether there is a
relation between depression and aging. It is known that the general
population averages μ = 40 on a standardized depression
test. The psychologist obtains a sample of n = 9
individuals who are all more than 70 years old. The depression
scores for this sample are as follows.
50, 47, 41, 49, 44, 42, 43, 47, 48
On the basis of this sample, can the psychologist conclude that
depression for...

1. A psychologist would like to estimate the average IQ of
Canadians. (IQ scores are known to follow a normal distribution
with standard deviation 15.) She takes a sample of 49 Canadians and
measures a sample mean IQ of 107.34 and a sample standard deviation
of 17.36.
(a) Use the information above to calculate a 92% confidence
interval to estimate the average IQ of Canadians.
(b) Interpret the confidence interval obtained in part (a).
(c) Suppose the researcher also wishes...

A psychologist would like to determine whether there is any
consistent relationship between intelligence and
creativity. The psychologist obtains a random sample of
n = 18 people and administers a standardized IQ test and a
creativity test to each individual. Using these data,
the psychologist obtains a Pearson correlation of r = +.20 between
IQ and creativity.
a. Do the sample data provide sufficient evidence to
conclude that a real (non-zero)
correlation exists in the
population? Test at the .05 level of significance.
b. If...

A developmental psychologist who wanted to know if children who
started walking earlier performed better in school divided 30
children into Early, Middle, and Late Walkers. At the end of the
second grade, the psychologist computed a composite performance
score based on teachers' reports and found no overall difference
between the groups: Early M = 2.94 (SD = .61); Middle M = 2.84 (SD
= .70); Late M = 2.77 (SD = .64); F (2, 27) = .86, p =...

A research psychologist wishes to investigate the difference in
maze test scores for a strain of laboratory mice trained under
different laboratory conditions. The experiment is conducted using
eighteen randomly selected mice of this strain, with six receiving
no treatment at all (control group), six trained under condition 1,
and six trained under condition 2. Then each of the mice is given a
test score between 0 and 100, depending on its performance in a
test maze. The experiment produced...
