The most common therapy for warts is cryotherapy, in which liquid nitrogen is applied to the area of the wart every few weeks, freezing it for a few seconds until the wart falls off. This isn't as painful as it sounds, but requries a physician's attention and, for some patients, is chilling to contemplate. An alternative therapy, presumably based on the theory that it works to fix everything else, is to put duct tape on the warts and leave it there for a week at a time until the wart goes away. In a randomized trial, 51 patients with warts were randomly assigned to a cryotherapy treatment or a duct tape treatment. Of 25 patients treated with duct tape, 20 had their warts completely cured. With the liquid nitrogen treatment, 17 of 26 patients were cured of their warts.
Provide the following in your answer:(i) appropriate null and alternative hypotheses, with alpha level.(ii) test the hypothesis using 2 different types of statistical tests. One of these you can showyour calculations for, the other you use a website applet, provided in the lab and in class notes.(iii) provide a concluding statement associated with each of the tests.
Gene frequencies for the ABO alleles vary geographically. For example the I^A allele makes up nearly 50 percent of the genes for blood type among Australian Aborigines, about 25 percent in Central Asian populations,

Suppose you are interested in studying dogs as a system for obesity. You crossed a Cocker Spaniel to a Labrador Retriever and interbred the offspring for many generations.
In an experiment you are studying a neuron that receives synaptic inputs from two other neurons: one from neuron A and one from neuron B. Illustrate a separate graph for each value of Vm.
During sleep, relay neurons in the thalamus reduce information reaching the cerebrum by altering their membrane potential. In diagnosing bacterial and viral infections of the nervous system, samples of CSF are extracted from the spinal cord.
There are 2-genes coding for beak color in peacocks. The R allele confers an orange beak, while r codes for a red beak. At a separate locus, the Spread gene.

Determine the percentage of offspring displaying each trait. If a single, diploid G2 nucleus in an ascus contains 400 nanograms (ng) of DNA, after that a single ascospore nucleus of this species should contain how much DNA (ng), carried on how many c..
This week's lab activities pertain to taxonomy and classification. For this week's discussion, I would like for you to try to recognize an example in your every day life or work life in which you utilize
