Biomass Exercise 7.65 reported that thebiomass for tropical woodlands, thought to be about35 kilograms per square meter (kg/m2), may in factbe too high and that tropical biomass values varyregionallyfrom about 5 to 55 kg/m2.21 Suppose youmeasure the tropical biomass in 400 randomly selectedsquare-meter plots and obtain x 31.75 and s 10.5.Do the data present sufficient evidence to indicate thatscientists are overestimating the mean biomass fortropical woodlands and that the mean is in fact lowerthan estimated?a. State the null and alternative hypotheses to be tested.b. Locate the rejection region for the test with a .01.c. Conduct the test and state your conclusions.
