There is a random sample of 65 invoices from 15025 invoices that were processed in the first two months of the new system’s operation. If the sample can be used to establish that the new billing system substantially reduces payment time, Vila Health does plan to quickly deploy it to the other hospitals within their system.
By looking at the payment times, we can see that the shortest payment time is 10 days and that the longest is 29 days. This does not tell us much information so it is important to perform a frequency distribution of the data and then graph the distribution by constructing a histogram.
For this assignment, the dataset is available as cf_ANLT_W2_InvoiceDayAndAmount.csv of the invoice payment days and the amount:
1.Determine the frequency distribution and construct the histogram:
Find the number of classes.
Find the class length.
Form the non-overlapping classes of equal width by defining the boundaries of the classes.
Tally and count the number of measurements in each class.
Graph the histogram.
2.Determine the skewness and kurtosis of the payment days.
3.Calculate the correlation between the payment days and the amount owed.
1.Explain how the correlation calculation shows the correlation between payment days and the amount owed.
2.Explain if the new billing system is more efficient than the old billing system based on the sample of the new system.
Your assignment will be graded on the following criteria:
Create the frequency distribution and histogram.
Explain the skewness and kurtosis on the sample data set.
Calculate the correlation of two variables.
Explain how the correlation calculation shows the correlation between two variables.
Explain if one billing system approach is more efficient than another based upon statistical analysis of a data set.
Provide a logical argument in support of conclusions or recommendations.

Japolli Bakery makes a variety of bread types that it sells to supermarket chains in the area. One of the problems is that the number of loaves of each type of bread sold each day by the chain stores varies considerably, making it difficult to know how many loaves to bake. A sample of daily demand data is contained in the file, Japolli Bakery.
1. Develop a frequency distribution for each bread type using
