A company that develops over-the-counter medicines is working on a new product that is meant to shorten the length of sore throats. To test their product for effectiveness, they take a random sample of 110 people and record how long it took for their symptoms to completely disappear. The results are in the table below. The company knows that on average (without medication) it takes a sore throat 6 days or less to heal 42% of the time, 7-9 days 31% of the time, 10-12 days 16% of the time, and 13 days or more 11% of the time. Can it be concluded at the 0.01 level of significance that the patients who took the medicine healed at a different rate than these percentages? After running a Goodness of Fit test, can it be concluded that there is a statistically significant difference in duration of a sore throat for those that took the medicine and what is the p-value? 6 days or less 7-9 days 10-12 days 13 or more days Duration of Sore Throat 49 40 12 9 Expected Counts 46.2 34.1 17.6 12.1 Yes, the p-value = 0.287801 No, the p-value = 0.712199 Yes, the p-value = 0.712199 No, the p-value = 0.287801

Lab Two Perform experiments 9-19: After you are done with experiment #8, your TA will assign the remaining experiments (#9-19). Your TA will give you instructions for the experiments. Record your results on the board/overhead in front of class. After completion of the experiments, record the results from both your experiments as well as the other people in class, and then fill out the worksheet. Notes: P20 set to 100 = 10 µl (the last digit is a decimal and will be in red) P200 set to 025 = 25 µl P1000 set to 1000 = 1000 µl (or 1ml) Also, note that some of the experiments use buffer alone, or ADP solution, and not the ATP solution. Chart of Experiments Quick Hints: Use 1 ml of the ATP, ADP, or buffer and if required add this to cuvette first Use 10 µl of the appropriate enzyme(s) and/or substrate(s) Mix reagents and incubate 5 minutes BEFORE adding 25 µl of the firefly extract Treatment/Experimental Condition Result (Light/No Light) Duration of Light 1. ATP alone 2. Hexokinase/ATP 3. D-Glucose/ATP 4. Hexokinase/D-Glucose/ATP 5. Buffer Alone (no ATP) 6. ADP alone (no ATP) 7. Phos.Creatine+CreatPhoskinase + ADP (no ATP) 8. Hex/D-Glu + PhCreat+CrPhosKin +ATP Treatment/Experimental Condition Result (Light/No Light) 9. Hexokinase/L-Glucose/ATP 10. Hexokinase/Sucrose/ATP 11. Hexokinase/Mannose/ATP 12. Hexokinase/Fructose/ATP 13. Hexokinase/Arabinose/ATP 14. Hexokinase/Maltose/ATP 15. Hexokinase/Ribose/ATP 16. Hexokinase/Lactose/ATP 17. Hexokinase/Erythrose/ATP 18. Hexokinase/Galactose/ATP 19. Hex/D-Glu/PhCr/CrPhK in Buffer (no ATP) Answer the following questions in the separate worksheet: Thinking about assay experiments 1 through 5, answer the following: What is the hypothesis that these experiments (1-5) are designed to test? Did they support or reject that hypothesis? Which experiments/cuvettes (1-5) are controls? What parameters does each cuvette control for in the overall experiment? In other words, for each cuvette listed as a control, what part of the overall hypothesis test would you be unsure of if you hadn't run it? Thinking about assay experiments 6 through 8, answer the following: What hypothesis do you think these experiments (6-8) are designed to test? Did they support or reject that hypothesis? Which experiments/cuvettes (6-8) are controls? What parameters does each cuvette control for in the overall experiment? In other words, for each cuvette listed as a control, what part of the overall hypothesis test would you be unsure of if you had not run it? Thinking about the lab overall and experiments 9-18, answer the following questions: Why do you think enzyme concentrations are often listed in activity units (i.e., concentration of substrate consumed per minute/ml) rather than absolute concentration (mg/ml or molarity)? When Hexokinase/Glucose and CreatPhosKin/Phosphocreatine reactions are running concurrently, what will determine which set of reactions will predominate or react the longest? We ran this experiment in cuvette 8. Which reaction ran the longest? Explain how you determined this and explain specifically why that reaction predominated. Looking at the results of your group and your classmates with regards to tests 9 - 19, what hypothesis can you draw from the results with respect to hexokinase's substrate specificity? Tip: You might want to organize your hexokinase-sugar data by grouping together data from sugars with equivalent numbers of carbons, then looking to see whether all 4 carbon sugars react similarly, 5 carbon sugars, disaccharides etc. Note that to do this you will have to look up the number of carbons of each sugar. For those sugars which are disaccharides, you may want to look at which two monosaccharides they are composed of.

A materials scientist claims that his new curing process for a particular type of cement results in a mean compressive strength of at least 5000 kg per square centimeter. You suspect that the figures are exaggerated. Formulate your null and alternative hypotheses for the needed test of significance. John is busy filling up chocolate chip bags in anticipation of the baking season. Their bags are labeled to hold 12 oz of chocolate chips each. They want to make sure that their machinery is accurately calibrated. If they want to test for this, how will they set up their null and alternative hypotheses? The Average Pumpkin Patch claims that their princess pumpkins have a mean weight of at least 12 lbs. You suspect they are embellishing the truth somewhat. Your plan is to bring a small child to find 40 pumpkins (at random, because small children are perfect random number generators) and weigh the pumpkins. How are you going to formulate your null and alternative hypotheses for this test of significance? The Electabuzz Electric Institute (EEI) studies the electricity consumption of a variety of appliances. The manufacturer of a particular type of leaf blower claims that the mean consumption is less than 36 kilowatt hours per year for a typical household. EEI suspects the contrary and they plan a study of randomly chosen households using that particular brand of leaf blower. How are they going to formulate their null and alternative hypotheses? The lifetime of a particular computer screen is advertised to have a mean of at least 900 hrs. A consumer rights agency wants to test this claim. How is the consumer rights agency going to formulate the null and alternative hypotheses?
