distributed with a mean lifetime of 500 days and a standard deviation of 60 days. A) Find the z-score for 575 days B) What is the probability that battery will last more than 524 days? C) What is the probability that a battery will last between 440 days and 524 days?
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.
For large samples of hearing aid batteries, battery life is normally distributed with a
Given mean = 500 days and
standard deviation = 60 days.
We have to find z-score and probability of the following..
