A person sees a Latino man and assumes he is an immigrant who crossed the border illegally. This is an example of:

Scenario Researchers collected intelligence test scores on twins, one of whom was raised by the natural parent and one of whom was raised by foster parents. The data set consists of test scores for the two groups, boys raised by their natural parents and boys raised by their foster parents.   Select the single best answer concerning a violation to independence.

Select all responses that are valid in the given scenario. In each scenario assume that the assumption of independence is satisfied and we want to compare the mean or median output/response of 3 treatment groups.

Consider the following ANOVA table and select all responses that are true                                  Df     Sum Sq      Mean Sq    F value        Pr(>F)     Treatment Group     2       1755           877.5         ______       0.000493 *** Residuals                 23      1869            81.3                      

Therapeutic Marijuana Description To investigate the capacity of marijuana to reduce the side effects of cancer chemotherapy, researchers performed a double-blind, randomized, crossover trial. Fifteen cancer patients on chemotherapy were randomly assigned to receive either a marijuana treatment or a placebo treatment after their first three sessions of chemotherapy. They were then crossed over to the opposite treatment for their next 3 sessions. In addition there were several observations that were censored as the observation was cut off due to the observation window (time the study used for completion). The boxplot has one group labeled as placebo and note the unlabeled group in that graph is the treatment group.

Consider the following statements by Dr. Fauci and ‘Rep. Blaine Luetkemeyer concerning the COVID-19 treatment of hydroxychloroquine: Rep. Blaine Luetkemeyer from Missouri, a Republican from Missouri, asked Fauci about the study and said that a doctor told him if zinc is involved, the drug (hydroxychloroquine) would work. Fauci responded by breaking down the study, saying it was a non-controlled, retrospective cohort study that had “a number of issues.” Those include, according to Fauci, the fact that people who received hydroxychloroquine were also using corticosteroids. “We know from another study (corticosteroids) gives benefit in reducing deaths with advanced disease,” he said. “That study is a flawed study, and I think anyone who examines it carefully is that it is not a randomized placebo-controlled trial…. Fauci added that when he does see a randomized, placebo-controlled trial that looks at the drug’s usage that shows effectiveness, “I would be the first one to admit it and promote it.” Select all answers that apply.
