A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 242 vinyl gloves, 66% leaked viruses. Among 242 latex gloves, 10% leaked viruses. Using the accompanying display of the technology results, and using a 0.05 significance level, test the claim that vinyl gloves have a greater virus leak rate than latex gloves. Let vinyl gloves be population 1.

In a study published in the American Journal of Psychiatry
researchers wanted to measure the effect of alcohol on the
development of the hippocampal region (responsible for long term
memory storage) in adolescents. The researchers randomly selected
12 adolescents with alcohol use disorders. They wanted to determine
whether the hippocampal volumes in the alcoholic adolescents were
less than the normal volume of 9.02 cubic centimeters HA:μ<9.02
. An analysis of the sample data revealed that the hippocampal
volume is approximately...

Question 1c (0.5 pts): In a study published in 2016, a team of
researchers found that tensile strain caused the valence band of an
organic semiconductor to narrow and fall to lower energy levels
without affecting the conduction band. What do you think this means
for the electrical conductivity of the material when placed under
tensile strain? Why do you think this occurs?
