(b.) State the means, +/- standard deviation (including units) and the supporting p-values. (c.) Interpret this result. (i.) If YES –you are able to REJECT the null hypothesis and infer that the two sets of measurements seem to be statistically different… Was this difference significant? highly significant? Suggest an explanation of why there appears to be a statistical difference of lengths measured between the paramecia samples –prepared mount versus freshly stained samples. That is, based upon your statistical analysis, can it be concluded that these species are different? Explain your answer. (ii.) If NO –you FAIL TO REJECT the null hypothesis and infer that the two sets of measurements do not seem to be statistically different… Suggest an explanation of why there appears to be no difference in means of lengths measured between the paramecia samples –prepared mount versus freshly stained samples. That is, based upon your statistical analysis, can it be concluded that these species are the same? Explain your answer. Are these data sets just similar by chance? Are there confounding factors? Is the sample size too small? Would increasing the sample size allow for better conclusions? How could the experimental design be improved? (15) Based on your experience in this exercise, report in tabular form at least two advantages and two disadvantages of permanent dry mounts versus wet mounts for determining features of specimens as observed by brightfield microscopy.
