a) Using (30, 80] as your first class, summarize this data by creating a table including the frequency, relative frequency (% corrected to 2 decimal places) , and cumulative relative frequency (corrected to 2 decimal places).

b) Using your table, how many sales of coil wire were for lengths greater than 80 mm or less than equal to 180 mm?

c) Using your table, what proportion of sales of coil wire were less than or equal to 130mm?

d) State the units of measure for this data.

e) Here is a boxplot of the lengths for this sample of data.
