The dead specimen was a disadvantage when looking at cell function. Movement The movement of the living specimen was a disadvantage because it was hard to focus in on and capture a good picture. The dead specimen did not move at all making it an advantage. It was easy to focus on and take a picture. Storage This is a disadvantage because you cannot store and reuse wet mount slides. This is an advantage because dry mounts are easily stored and reused. Staining Because you do not have to stain the specimen to identify it, this is an advantage. **Could be seen as disadvantageous because stains are easier to detect. This is a disadvantage because time has to be taken to stain the specimen. **Also could be seen as an advantage because the stain makes it easier to identify the specimen. Exercise 1 Page of 3 5

Dry Mount ParameciaWet Mount Paramecia (c)Based on the length measurements, do the Parameciaused for the permanent dry mount and the sample of Parameciaused for the wet mount likely belong to the same species? State the null hypothesis concerning these sets of measurements. Use the class data set to perform a t-test and support your conclusion when explaining your answer. Provide the means, standard deviations (including units) and p-values. Interpret the results. (i)If the p-value indicates a statistically significant difference: Can you reject the null hypothesis and infer that the two sets of measurements reflect a real and meaningful difference? Can it be concluded that these two sets of Parameciareally belong to two different species? Suggest an explanation for this difference. (ii)If the p-value indicates a lack of a statistical difference: Does this indicate that the null hypothesis has been confirmed? Explain your answer, taking into account sample sizes, experimental design (e.g., wet vs.dry specimens), and possible confounding factors.
