Researchers aim to find a topical solution for skin cancer in its early stages to avoid surgery.They believe Curcumin is effective, however, it must be solubilised in a solution as a carrierto be applied on skin. Solvability is one important factor because a solution with highersolvability contains a higher amount of curcumin. For this reason, an experiment wasdesigned by researchers to examine and compare the solvability of 5 popular solutions. Priorto starting the experiment, a company asked the researchers to use and examine their newadditive solution "X" by adding the additive to the solutions. The company claims that theadditive significantly increases the solvability of the solutions. The researchers test thesolvability of their 5 solutions first and then redo all the steps again by adding "X" to theirsolutions. There are 5 replicates for each solution in each test. The results are displayed in thetable below:Withoutadditive "X"Withadditive "X"Water1.11.11.31.41.29.38.110.88.810.75Ethanol108.59.210.2912.29.39.810.511.7Solvability mg/mlCapryol9.459.210.28.99.59.58.79.18.28.2Labrafac21.8524.423.522.6524.12725.828.828.427.1Labrasol52.149.955251.852.549.353.251.148.550.2a) Run a two independent samples t-test in the statistical software package of your choice forbefore and after adding solution "X" and interpret your finding.Do you think this test can tell us anything about using the additive or not?

Evaluation: More Than 48 Grams 1. A chemical engineer is trying to increase the amount of the useful product in a reaction. She performs the reaction with her new equipment 10 times and gets the following amounts of the useful product: Amount of Useful product in Grams 47.1 48.2 48.3 47.5 48.5 48.1 47.2 48.2 48.4 48.3 What proportion of the reactions were above the 48 grams threshold? 2. Other chemists typically get 65% of their reactions to produce more than 48 grams. Should the engineer say that she was able to increase the useful product when compared to the other chemists?
