Some biology students were interested in analyz- ing the amount of time that bees spend gathering nectar in flower patches. Thirty-nine bees visited a high-density flower patch and spent the following times (in seconds) gathering nectar: 235 210 95 146 195 840 185 610 680 990 146 404 119 47 4 10 169 270 95 329 151 211 127 154 35 225 140 158 116 46 113 149 420 120 45 10 18 105 Based on the collected random sample of size 39, (1) Find a point estimate of the population mean spent time in seconds, and state which estimator you used. (2) Find the point estimate of the population standard deviation of the spent time for gathering nectar. State which estimator you used. Interpret the result. (3) What is the point estimate of the proportion of all bees that spend less than 550 seconds to finish the nectar gathering.
