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.

No, the result from part (a) could not be the actual number of adults who said that they play basketball because a count of people must result in a whole number. O B. Yes, the result from part (a) could be the actual number of adults who said that they play basketball because the results are statistically significant. O C. No, the result from part (a) could not be the actual number of adults who said that they play basketball because that is a very rare activity. O D.

You will simulate shooting basketball free throws. Using any coin, let heads represent the ball going into the basket and tales represent the ball missing the basket. Each toss of the coin represents a shot at the free throw line. Simulate shooting 35 free throws. Make a chart on your paper similar to the one below to record your results. For each trial (toss), place an x in the appropriate column. Toss number 1 2 Went in (Heads) X Questions: 1. How many free throws went into the basket? 2. How many free throws missed the basket? Missed (Tails) X 3. What is the experimental probability that you will make the next free throw? 4. What is the experimental probability that you will miss the next free throw? 5. This simulation assumes that you have an equal chance of making the free throw or missing the free throw. Is this a correct assumption? Why? 6. How would you change this simulation to better predict a person's abilities at making free throws?
Researchers conducted a study to find out if there is a difference in the use of eReaders by different age groups. Randomly selected participants were divided into two age groups. In the 16- to 29-year-old group, 7% of the 630 surveyed use eReaders, while 11% of the 2,303 participants 30 years old and older use eReaders. (Use ? = 0.05. For subscripts let 1 = 16- to 29-year-old users, and 2 = 30 years old and older users.) State the Distribution of the test: P'1- P'2 ~ N( _ , _ ). I found the standard deviation as .0136. So now I just need the fill in. P'1- P'2 ~ N( x , .0136). What is x? Thank you!
