42	15	20	6	34	19	8	5	11	38	56	23	24	24
35	47	22	36	39	18	14	44	25	6	34	35	28	12
27	32	36	34	30	40	32	12	17	6	37	32

(1) Construct a frequency table for this data using class intervals 0 - 9, 10 - 19, ..., 50 - 59. (2) Hence draw a column graph to display the data. (3) Write down the modal class. (4) What percentage of the streets contain at least 20 houses?
