How would you determine if this represented a real difference in enzyme activity between students, as opposed to a pipetting error or other error?
Homework Answers
In the represented data, if there is a difference in the enzyme activity calculated between students; There can be possibility that
1. difference in enzyme activity really exists
2. Difference is observed due to pipetting error
3. Difference exists because of use of reagents from different manufacturers or different batches of the product
4. Difference can be due to the experimental setup wherein temperature and humidity is involved
We can figure out the exact reason from by cinsidering data presented by different student groups. By evaluating the consistency of data between different student groups, the conclusion can be reached. If there is lot of deviation in the data among different groups and none of data set is matching then definatley it is not correct enzyme activity.

How you would determine an enzyme regulation? Below is a series of results from tests of one particular enzyme. List all the potential methods of regulation still possible after each test. The options are: "genetic" control, zymogenic, phosphorylation, competitive inhibition, noncompetitive inhibition, positive allosteric regulation, and irreversible inhibition. 1. The enzyme is always present in the cell. 2. All tests only slow enzyme activity. 3. Adding more substrate does not increase reaction rate. 4. There seems to be a form...

Does anyone know how to do this? Thanks in advance!
Enzyme Activity (ml) Effect of pH on (amylase) enzyme activity. For determination of optimum assay pH of the enzyme reaction, 0.05 M Na2HPO4-NaH2PO4 buffer was used. The reaction was carried out for 10 min at 50°C in a shaking water. The enzyme activity was measured and the results are presented on graph, Bars represent means standard deviations for three replicates. 1. What do the error bars in this graph represent?...

5. Consider running a test on the proportion of students who are doing regular physical activity. You are trying to disprove the claim that 30% of students do regular physical activity, and therefore choose the following hypotheses Ho:p=0.3 H, : p 0.3 and plan to use a 5% significance level. Calculate the prob- ability of committing a type II error when using a sample of n 50 students, assuming the true proportion is 0.4. In other words, find β(0.4).

Dr. Cribari would like to determine if there is a statistically significant difference between her two Math 2830 classes. To make this comparison she will compare the results from exam 1. Class one had 35 students take the exam with a mean of 82.6 and a population standard deviation of 1.41. Class two had 32 students take the exam with a mean of 84 and a population standard deviation of 3.63. Can Dr. Cribari conclude that there is difference in...
