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.

On 15 May 2019, 4000 drivers were tested and 98 were above this level What additional information would you require before trying to draw a conclusion from these data?
- A new drug is released to market and it has been determined that the drug is responsible for causing hypertension among those individuals who take the drug if 30276 individuals were prescribed the drug in its 1st year on the market and 17620 individuals developed hypertension what is the point prevalence of hypertension among those individuals described the drug after the drugs 1st year on the marketIf the alleles A and B of the cystic fibrosis gene occur in a population with frequencies p and 1 - p (where pis between 0 and 1), then the frequency of heterozygous carriers (carriers with both alleles) is 2p(l - p). Which value of p gives the largest frequency of heterozygous carriers?Let's assume that there are 500 people in a population. The researcher has access to all 500 participants, and sends a questionnaire that is accessed by a hyperlink. Of the 500 possible subjects, 485 complete it. Does this mean that the results generated from this study will be highly-accurate? What might cause the study to be unreliable?

- The international Human Genome Project yielded the DNA sequence of all 23 human chromosomes, each consisting of millions of nucleotides chained end to end. These encode the genes whose products-RNA and proteins-shape the growth and development of each individual. The length of each gene refers to the total number of nucleotides comprising the coding regions. A random sample of 100 human genes from the human genome was found to have a median length of 2640.5 nucleotides. Select the true statement(s) about the obtained median. A). The median gene length of all human genes is estimated to be 2640,5 nucleotides. B). A random sample of 1000 genes would likely yield an estimate of the median closer to the population median than a random sample of 100 genes. C). The sample median has a sampling distribution with a standard error. D) The median gene length of all human genes is 2640.5 nucleotides.A research study in a big metropolitan area shows that 2% of individuals living within the city limits move to suburbs during one-year period while 1% of individuals living in the suburbs move to the city during a one-year period. 1.

The temperatures of a sample of individuals were obtained before the boosters were given. The following day, their temperatures were again measured. The table below shows the data in degrees Celsius. (10 points) Temperature before Temperature after one day. Determine If there is a significant difference in the average temperature of Individuals who were given boosters at 5% level of significance. Assume that the differences in the temperatures follow the normal distribution.
