There is some concem that il women over age 59 who take supplemental hormones also drink alcohol, their hormone levels will rise too high. Seventeen volunteers on hormone therapy were randomly divided into two groups, as were 18 other volunteers not on hormone therapy, In each case, one group drank an alcoholic beverage, the other a nonalcoholic beverage. An hour later everyone's hormone level was checked. Only those on supplemental hormones who drank alcohol showed a marked increase a) Identify whelther the above research is an observational study or an experiment The described research is an b) Identify the subjects studied The subjects were c) Identify the factor(s) in the experiment, and the number of levels for each.

In peas, gray seed color is dominant to white. True breeding peas with gray seeds were crossed with true breeding peas with white seeds. In the F1 generation all progey had gray seed color. In the F2 generation the following progeny were observed: 320 with gray seeds and 80 with white seeds. Use a chi-square test to determine if these numbers fit the expected Mendelian ratio for this cross.
