Selected Technologies According to recent surveys, 60% of households have personal computers. If a random sample of 175 households is selected, what is the probability that more than 65 but fewer than 95 have a personal computer? Round z-value calculations to 2 decimal places and final answer to at least 4 decimal places. P (65< X< 95)
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.
