Mean susceptibility for the population

Reference no: EM131019822

An experiment is conducted to examine the susceptibility of root stocks of a variety of lemon trees to a specific larva. Forty of the plants are subjected to the larvae and examined after a fixed period of time. The response of interest is the logarithm of the number of larvae per gram that is counted on each root stock. For these 40 plants the sample mean is 9.02 and the standard deviation is 1.12. Use these data to construct a 90% confidence interval for m, the mean susceptibility for the population of lemon tree root stocks from which the sample was drawn. Assume that σ can be replaced by s.
