Explain at least one possible reason why you might have the following results in an agarose gel electrophoresis of your PCR products. In addition to your DNA PCR sample, you also ran a Hi-Lo Marker, a positive PCR control, and a negative PCR control. 16. Scenario C: Your Hi-Lo marker showed up but there were no bands in the lanes for your PCR positive control, DNA PCR sample or negative PCR control.

Question 1 Tests comparing 2 population means can be: surveys experiments both surveys and experiments Question 2 If all the experimental units are identical (ex: clones), you will set up the study as: CRD Block Design Question 3 a 2 sample t-test still has which normality assumption(s)? The population is normal or n is greater than 30 both populations are normal or both sample sizes are greater than 30 Question 4 When you block by some variable in a block...

CAN YOU PLEASE FIX MY LAST TWO SENTENCES WITH THIS INFORMATION? You note in your report both the t critical for a one tailed and a two tailed test. Identify whether you need to use a one tailed or a two tailed test for the test statistic and t critical. Then only compare the test statistic with that critical value. Otherwise when you mention both, it looks like you don't know which one to use. t-Test: Two-Sample Assuming Unequal Variances...

If one wants to test whether there is a difference in mean scores before and after an exam, which will be an appropriate test to use? a) one sample z test b) one sample t test c) paired t test d) two sample independent t test If X is a random variable following a Uniform(a,b) distribution, which option represents an approxi- mate shape of its density function? a) straight vertical line between a and b b) straight horizontal line between...

Results You will actually want to decide what you intend to show in your results before you work through your materials and methods. You have to first ask yourself, "What am I trying to prove?" before you can work out, Here's how I'm going to go about proving it." You will need at least two graphs for your results, which means that you need at least...

Assignment #11 Single Sample t-Test What factor determines whether you should use a z-test or a t-test statistic for a hypothesis test? 11.1 A sample is selected from a population mean of u 30. A treatment is administered to the individuals in the sample and, after treatment, the sample mean found to be M 11.2 = 31.3 with a sample variance of s2 9 If the sample consists of...

Please give as much detail as possible. Your help is seriously appreciated. Predicting the Weather One of the places we tend to see probability use on a regular basis is the weather channel. For this assignment, you will use the binomial distribution to make weather-related predictions, and ultimately compare two locations. New York State: In New York State, in April, the probability of snow happening on any given day is 0.3. Knowing this, use the binomial distribution (and your graphing...
