The sаmple size, meаn аnd standard deviatiоn were already calculated fоr the cоntrol group of froglets (those that were given the natural algae food). These were the values for the control group: gApply the significance test used in the lab manual (comparing the test ranges calculated as   for each group) to determine if there was a significant difference in the growth of the tadpoles between the control and experimental groups. You will have to use your calculated mean and standard deviation for the experimental group and the mean and standard deviation given here for the control group. Calculate the high and low values for the significant test ranges for the (A.) control group and for (B.) the experimental group.Report your answers in the following format on the first two lines:A. (2 Points) "Control group test range: [high value] to [low value] g"B. (2 points) "Experimental group test range: [high value] to [low value]"(Example for the first one: A. Control group range: 20.5 to 17.8 g)Based on your ranges indicate if your null hypothesis is supported or if your null hypothesis is rejected in favor of the alternate hypothesis. Use the following format to type the answer on the third line: C. (1 point) "The null hypothesis is _______." In the space below, type the letter A. before typing your response in the format described above. Then type B. before typing you second response in the format described above for B. Do the same for part C.
