Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 78.4 Mbps. The complete list of 50 data speeds has a mean of x= 17.74 Mbps and a standard deviation of s 22.75 Mbps a. What is the difference between carrier's highest data speed and the mean of all 50 data speeds? b. How many standard deviations is that (the difference found in part (a))? c. Convert the carrier's highest data speed to a z score, d. If we consider data speeds that convert to z scores between - 2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant? a. The difference is Mbps. (Type an integer or a decimal. Do not round Y b. The difference is standard deviations. (Round to two decimal places as needed.) c. The z score is z= (Round to two decimal places as needed.) d. The carrier's highest data speed is

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.
