Independent Samples t-test 3. A behavioral researcher wished to determine whether or not 10 milligrams of Valium would have an effect on the scores of human subjects performing a task of psychomotor coordination. Students were selected from a subject pool and an equal number assigned to Experimental (Valium) and Control conditions. All subjects in the Experimental Group received Valium thirty minutes prior to being tested. The subjects in the Control Condition received a placebo (inert substance) at the same time. Higher scores represent superior psychomotor coordination. Using an alpha of .05, perform an appropriate two-tailed test of the significance of the mean difference.

Pain medications sometimes come with side effects. One side effect is dizziness. A researcher wanted to determine if some pain medications produced more or less dizziness than others. The results from his study are shown in the table below.

Infectious Disease Commonly used vaccines for influenza are trivalent and contain only one type of influenza B virus. They may be ineffective against other types of influenza B virus. A randomized clinical trial was performed among children 3 to 8 years of age in 8 countries. Children received either a quadrivalent vaccine (QIV) that had more than one influenza B virus or a trivalent Hepatitis A vaccine (control). An attack rate (i.e.,% of children who developed influenza) starting 14 days after vaccination until the end of the study was computed for each vaccine group, stratified by age. The following data were reported. age QIV group 3-4 5-8 3.75 1.71 Control group 5.64 5.17 (a) Suppose 3 children in a village ages 3, 5, and 7 are vaccinated with the QIV vaccine. What is the probability that at least one child among the 3 will get influenza? (Round your answer to four decimal places.) (b) Suppose that 80% of 3-4-year-old children and 70% of 5-8-year-old children in a village are…
