Suppose X=N(10, 1.924)Pr(7.6 less than X less than 9.3)
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.
Suppose X=N(10, 1.924)
Pr(7.6 less than X less than 9.3)
In this question we have X as random variable which follows normal distribution with mean = 10 and variance = 1.924.We have to find the probability that is given on whiteboard
We have used the method of calculating the probability for normal distribution by changing it to standard normal. The complete procedure is given on white board. To get values of Z we had use the “Probabilities for Standard Normal distribution“ P (Z < 0.50) is 0.69146 and P(Z<1.73) is 0.0418.
