Problem 19

Using the EOM, ROG, and Extra dating methods, calculate the discount date and the net date for the following transactions. Unless otherwise specified, the net date is 20 days after the discount date. May 18 4/25, EOM

Step-by-Step Solution:
Step 1 of 3

STAT 2004 CHAPTER ONE: WEEK 4 SAMPLE STATISTICS n 2 1 2  Sample variance- s = n−1 i=1x ix´)  Sample standard deviation- Tells you how spread out your data is. It is the square root of the variance. QUANTILES  Also known as percentiles. o If you are in the 70 percentile, you are better than 70% of your class and not as good as 30%. DISTRIBUTION  Describes shape, center, and spread/variation of data. For the images below, imagine histograms that fit the depicted curves. BOXPLOT  A boxplot uses a five number summary consisting of the median (Q ), 2 minimum, maximum, and 25 (Q ) and 75 (Q ) percentile. It 1 3 summarizes a data set while also plotting unusual observations known as outliers. o Outliers- Observations that are extreme relative to the rest of the data.  Below is an example of a boxplot depicting test scores. Boxplots are usually vertical, but this one will be depicted horizontally. o The first step is to draw the median. The second step is to draw a rectangle to represent the middle 50% of the data.  Interquartile range (IQR)- Q3-Q1. It is the length of the box in the boxplot.  IQR Method o One of the many methods for calculating outliers.  Lower cut
