2. The data show prices of light bulbs at a home improvement store, rounded to the nearest dollar. 5, 2, 8, 10, 2, 20, 6, 15, 29, 6, 2, 2, 5, 1, 3 (a) Find the five-number summary of the data set. (b) Find the range and interquartile range (IQR) of the data set. (c) Draw a box plot of the data set.

Summarize the data given in the problem:

{2, 5, 8, 2, 20, 6, 15, 29, 6, 2, 2, 5, 1, 3}

arrange the numbers in order:

{1, 2, 2, 2, 2, 3, 5, 5, 6, 6, 8, 15, 20, 29}

The interquartile range (IQR) of the data set:

Population size: 14

Find the lower quartile value (x_L) : 2

upper quartile value (x_U) : 9.75

Interquartile range is (x_U-x_L) = 7.75
