Relative frequency summary of sample data

Reference no: EM131002498

The table below shows a relative frequency summary of sample data on distances between DNA replication origins (inter-origin distances), measured by Li et al., (2003)5 , with an in vitro Xenopus egg extract assay in Chinese Hamster Ovary (CHO) cells, as reported in Chapter 7 of Birtwistle (2008)6.

Inter-Origin Distance (kb) x	Relative Frequencyfr (x)
0	0.00
15	0.09
30	0.18
45	0.26
60	0.18
75	0.09
90	0.04
105	0.03
120	0.05
135	0.04
150	0.01
165	0.02

(The data set is similar to, but different from, the one in Application Problem 9.40 in Chapter 9.) Obtain a histogram of the data and determine the mean, vari- ance and your best estimate of the median.
