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.

Transcribed Image Text:Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure
taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the
heartbeat. Blood pressures were measured, in millimeters, for a sample of 8 adults. The following table presents the results.

The least-squares regression line y = b,+b,x 89.6478 – 0.0966x and E (x-x)
P-value method to test H:B, =0 versus H, : B, <0. Can you conclude that systolic blood pressure is useful in predicting
diastolic blood pressure? Use the a = 0.10 level of significance and the TI-84 calculator.
