The following table lists length of stay (days) in hospital for a sample of 25patients5,10,6,11,5,14,30,11,17,3,9,3,8,8,5,5,7,4,3,7,9,11,11,9,41(a). Construct a frequency/relative frequency table for these data using 5days class intervals. Include coloums for the frequency counts,relative frequencies and cumulative frequencies.(I)what percentage of hospital stays were less than 5days?(ii)what percentage of hospital stays were less than 15days?(ii)what percentage of hospital stays were at least 15days in length?1b (I) using the above data calculate the mean,median and mode (ii) explain why the mean and madian are different
I am in PSYCH STATISTICS. I am populating a frequency distribution chart (13,14,12,16,1211,13,17,16,13) the first column is X. below X each box (7 of them ) has a number (a1,a2,a3,a4,a5,a6,a7) I believe each box below X gets filled with the DATA NUMBER (from 11-17) . 1 Question #### There are only 6 Data numbers and 7 spaces (a1 - a7) #### The next Column is F ( I assume is the frequency of the data number. 2 Question There are 3 more columns. What do they stand for A) P B) CF C) PCT if possible can you completer the frequency distribution chart

One of the primary goals of constructing a frequency distribution for quantitative data is to summarize the data O by showing frequency of values that lie within a class or bin. O so that there are always 7 classes or bins of data. O ensuring that the classes or bins are always of different widths. O in a manner so that each class or bin has the same number of data points.
