Solar energy generation along highways. Refer to the International Journal of Energy and Environmental Engineering (December 2013) study of solar panels constructed above national highways to generate energy, Exercise 8.39 (p. 464). Recall that solar panels were constructed above sections of both east-west and north-south highways in India. The amount of energy (kilowatt-hours) supplied to the country’s grid by the solar panels above the two types of highways was determined each month. The data for several randomly selected months are reproduced in the table. Use a nonparametric test to determine if the distribution of monthly solar energy levels for northsouth–oriented highways is shifted above the corresponding distribution for east-west–oriented highways. Test using a = .05. Month East-West North-South February 8658 8921 April 7930 8317 July 5120 5274 September 6862 7148 October 8608 8936 Source: From P. Sharma and T.
