49 randomly selected students were asked how many siblings were in their family. Let X - the number of pairs of siblings in the student's family. The results are as follows: # of Siblings 0 1 2 3 4 5 Frequency 7 11 8 4 9 10 Round all your answers to one decimal place. The mean is: The median is: The sample standard deviation is: The first quartile is: The third quartile is: What percent of the respondents have at least 2 siblings? % 54% of all respondents have fewer than how many siblings?
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.
49 randomly selected students were asked how many siblings were in their family. Let X - the number of pairs of siblings in the student's family. The results are as follows:
| # of Siblings | 0 | 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|---|---|
| Frequency | 7 | 11 | 8 | 4 | 9 | 10 |
