The following null and alternative hypotheses are given: Ho : u = 950 H : u > 950 where the standard deviation o = 48, and the sample size n 26. Part A Write the expression of the transformation from x-values to z-values: Z = Use mu for the mean, u sigma for the standard deviation, a x for the random variable, X n for the sample size, n sqrt( ) for the square roots. Part B Write the critical z-value of standard normal distribution (from spreadsheet or look-up tables): Za For this test take a 0.07. Part C Calculate the upper and lower x-values corresponding to critical z-values, za and - za, respectively: Tcrit,U

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.
