Two autosomal loci control horn color in unicorns. Pure-breeding gold-horned unicorns were mated to pure-breeding bronze unicorns. The F1 were all silver. The F2 generation consisted of 9 gold, 7 bronze, and 22 silver unicorns. Use these data to hypothesize the type of epistasis that is operating here. Ho: The mode of inheritance for horn color in unicorns is A larger experiment was conducted to test the null hypothesis. The F2 generation in the larger data set consisted of 126 bronze-horned unicorns, 166 gold horned unicorns and 392 silver horned unicorns. Conduct the Chi-square test using the larger data set.

Migraine and Acupuncture: A migraine is a particularly painful type of headache, which patients sometimes wish to treat with acupuncture. To determine whether acupuncture relieves migraine pain, researchers conducted a randomized controlled study where 164 patients diagnosed with migraine headaches were randomly assigned to one of two groups: treatment or control. 70 patients in the treatment group received acupuncture that is specifically designed to treat migraines. 94 patients in the control group received placebo acupuncture (needle insertion at non-acupoint locations). 24 hours after patients received acupuncture, they were asked if they were pain free. Results are summarized in the contingency table below. Test to see if migraine pain relief is dependent on receiving acupuncture. Use a = 0.05.

A study indicates that CB radio use speeds up activity in the brain. As part of a randomized crossover study, 36 participants were fitted with a CB radio device on each ear and then underwent two positron emission topography, or PET, scans to measure brain glucose metabolism. During one scan, the CB radios were both turned off. During the other scan, an automated 40- minute muted signal was sent to the radio on the right ear. The order of when the signal was received (for the first or second scan) was randomized. Comparison of the PET scans showed a minor increase in activity in the part of the brain closest to the antenna during the transmission of the automated signal. Was this an observational study or an experiment? Explain why. O The study is an observational study because the reseashers cannot control the response variable during the signal. O The study is an observational study because the researchers only observe values of the response and explanatory variables. O The study is…
Migraine and Acupuncture: A migraine is a particularly painful type of headache, which patients sometimes wish to treat with acupuncture. To determine whether acupuncture relieves migraine pain, researchers conducted a randomized controlled study where 161 patients diagnosed with migraine headaches were randomly assigned to one of two groups: treatment or control. 65 patients in the treatment group received acupuncture that is specifically designed to treat migraines. 96 patients in the control group received placebo acupuncture (needle insertion at non-acupoint locations). 24 hours after patients received acupuncture, they were asked if they were pain free.

Assortative mating is a nonrandom mating pattern where individuals with similar genotypes and/or phenotypes mate with one another more frequently than what would be expected under a random mating pattern. Researchers studied this topic and collected data on Scandinavian men and their female partners. They found out 60% of Scandinavian men have blue eyes. Among those men with blue eyes, 80% of them choose female partners with blue eyes. Among those Scandinavian men whose eye color is not blue, 20% of them have partners with blue eyes. Given that a man’s partner has blue eyes, what’s that probability this man has blue eyes? If 60% of Scandinavian men have blue eyes and you randomly select 8 men, what’s the probability that none of them has blue eyes?
The Salk vaccine against polio was tested in 1954 in a carefully designed field experiment. Approximately, 400,000 children took part in this experiment. Using a randomization procedure, the children were randomly divided into 2 groups of equal size, a treatment group, and a control group. The vaccine was given only to the children in the treatment group; the control group children received placebo injections. The children did not know which of the two groups they had been placed into. The diagnosticians also lacked this information. 57 children in the treatment group went on to contract polio, while 142 children in the control group contracted the illness. How likely would such a difference in outcomes be when the assignment to the treatment or control group had absolutely no effect on the outcomes?
Recent research findings have shown that older people who practice ballroom dancing are 77% less likely to experience dementia compared to those senior citizens who did not dance. Drawing on this surprising result, Dr. Anders Ericsson thinks that ballroom dancing may also reduce one's level of stress to a greater extent than conventional exercise routines. To validate his claim Dr. Ericsson has randomly selected 100 senior citizens who were then randomly split into two groups, with the first group practicing ballroom dancing 3 times a week and the second group undergoing a conventional exercise regiment 3 times a week also. The measures of stress were assessed for each participant after the study was completed. What is the most appropriate set of hypotheses for this study?

In randomized, double-blind clinical trials of a new vaccine, children were randomly divided into two groups. Subjects in group 1 received the new vaccine while subjects in group 2 received a control vaccine. After the second dose, 123 of 460 subjects in the experimental group (group 1) experienced drowsiness as a side effect. After the second dose, 24 of 106 of the subjects in the control group (group 2) experienced drowsiness as a side effect. Does the evidence suggest that a different proportion of subjects in group 1 experienced drowsiness as a side effect than subjects in group 2 at the a = 0.01 level of significance? Determine the null and alternative hypotheses. Choose the correct answer below. A. Ho: P1 =0 versus Ho: P, #0 B. Ho: P =P2 versus H,: P, P2 The test statistic zo is (Round to two decimal places as needed.)
