They were each asked to provide percentile estimates of the time (x‚ in years) it would take the road to undergo a major maintenance after its completion. We seek to maximize this time variable x‚ as larger values imply better structural integrity as well as cheaper projection of the net

Graphological Deviation By graphology is meant the encoding of meaning in visual symbols. Deviation at this level seems to be much more interesting‚ but has been sadly neglected in literary discussions in the past.

help visualize the possibilities.) The law of independent assortment says that an organisms individual traits are passed in independently of one another.

1. Consider a sample with data values of 27‚ 25‚ 20‚ 15‚ 30‚ 34‚ 28‚ and 25. a) Compute the mean‚ median‚ and mode. b) Compute the 20th‚ 65th‚ and 75th percentiles. c) Compute the range‚ interquartile range‚ variance‚ and standard deviation. Answers: Data values: 15‚ 20‚ 25‚ 25‚ 27‚ 28‚ 30‚ 34 a) Mean: [pic]= ∑xi/n = (15+20+25+25+27+28+30+34) / 8 = 204 / 8 = 25.5 Median: Even number‚ so median is = (25+27)/2 = 26 Mode: Most frequent number = 25
