Equipment Breakdowns. A factory manager collected data on the number of equipment breakdowns per day. From those data, she derived the probability distribution shown in the following table, where W denotes the number of breakdowns on a given day. w 0 1 2 P(W = w) 0.80 0.15 0.05 a. Determine µW and σW . Round your answer for the standard deviation to three decimal places.b. On average, how many breakdowns occur per day?c. About how many breakdowns are expected during a 1-year period, assuming 250 work days per year?
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.
Equipment Breakdowns. A factory manager collected data on the number of equipment breakdowns per day. From those data, she derived the probability distribution shown in the following table, where W denotes the number of breakdowns on a given day.
| w | 0 | 1 | 2 |
| P(W = w) | 0.80 | 0.15 | 0.05 |
a. Determine µW and σW . Round your answer for the standard deviation to three decimal places.
b. On average, how many breakdowns occur per day?
c. About how many breakdowns are expected during a 1-year period, assuming 250 work days per year?
