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.

e. Based on this, we should (Select an answer v the null hypothesis.
f. Thus, the final conclusion is that ...
(Please show your answer to 4 decimal places.)
O The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude
that the mean innings per game for the eleven left handed starting pitchers that were looked
at is more than the mean innings per game for the eleven right handed starting pitchers that
were looked at.
O The results are statistically insignificant at a = 0.01, so there is statistically significant
evidence to conclude that the population mean innings per game for left handed starting
pitchers is equal to the population mean innings per game for right handed starting pitchers.
O The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude
that the population mean innings per game for left handed starting pitchers is more than the
population mean innings per game for right handed starting pitchers.
O The results are statistically insignificant at a = 0.01, so there is insufficient evidence to
conclude that the population mean innings per game for left handed starting pitchers is more
than the population mean innings per game for right handed starting pitchers.
g. Interpret the p-value in the context of the study.
O There is a 0.56% chance that the mean innings per game for the 10 lefties is at least 1.5
innings more than the mean innings per game for the 10 righties.
O If the sample mean innings per game for the 10 lefties is the same as the sample mean innings
