The length of human pregnancies from conception to birth varies according to a distribution that is approximately normal with the mean. 266 days and standard deviation, 16 days. If a random sample of size 16 pregnant women is taken from the population repeatedly and the mean length of pregnancies are calculated from the samples: a) Determine the standard error of the distribution of the sample means b) Write a probability distribution model for the sample mean.
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.
