Afarmer wants to know which of two fertilizers will yield the most produce. he sets up twenty random plots of equal size on one acre. none of the plots are contiguous. he prepares the soil of all 20 plots identically except for the choice of fertilizer, using fertilizer z on ten of the plots and y on the other ten. he plants the same number of seeds from the same batch in all 20 plots. throughout the growing season all 20 plots are maintained, watered, weeded, and treated exactly the same except that the ten plots that got fertilizer z get only that same fertilizer. all the y plots get only that fertilizer. when the produce is ready for harvest, he tracks the yield for each plot in weight. the results are shown in the table. z plots y plots 456 395 454 390 449 391 453 402 431 395 456 405 445 432 430 438 463 420 438 425 a. calculate the mean for sample z and for sample y. b. which sample will have larger measures of deviation from the mean? in two or more complete sentences, explain your answer.
