Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

What is the p-value?
Round your answer to four decimal places.
p-value = i

Transcribed Image Text:A study shows that exercise appears to offer some resiliency against stress. In the study, mice were randomly assigned to live in an
enriched environment (EE), a standard environment (SE), or an impoverished environment (IE) for several weeks. Only the enriched
environment provided opportunities for exercise. Half the mice then remained in their home cage (HC) as control groups while half
were subjected to stress (SD) by being placed repeatedly with a very aggressive mouse. All the mice in SD exhibited acute signs of
stress during these brief exposures to "mouse bullies." The researchers were interested in how resilient the mice were in recovering
from the stress after the mouse bullying stopped.' There were eight mice in each of the six groups, and conditions for the ANOVA
tests are met.
Time Hiding in Darkness
One measure of mouse anxiety is amount of time hiding in a dark compartment, with mice that are more anxious spending more
time in darkness. The amount of time (in seconds) spent in darkness during one trial is recorded for all the mice and the results are
shown in Table 1.
