- Calculate the statistic (with the notation) you will need to perform a hypothesis test.
- Perform a hypothesis test to determine whether there is a difference in proportion of those with the gene disruption who have dyslexia versus those with no dyslexia
- State the null and alternative hypotheses. DRAW/LABEL/SHADE a curve, and identify the resulting p-value
- At =.05 significance level, what is your conclusion for your test in context of the problem?

Researchers conducted a study to determine the effects of
different types of alcohol on the peak alcohol concentration. In
one part of the study, the researchers gave 15 randomly select
males a controlled volume of vodka and monitored the subjects'
alcohol concentration following the period of consumption.
The legal limit for driving is 80 mg/dL (milligrams per
deciliter of blood). A hypothesis test was conducted to see if the
mean peak alcohol concentration from drinking vodka was different
from the...

Researchers conducted a study on how the number of powerboats
registration may affect the number of manatees killed between year
of 1977 and 1990. The data set is contained in the file boat.xlsx.
Use Excel to open the data set. The first column is the year, the
second column is the number of powerboats registration (in
thousand), and the third column is the number of manatees
killed.
1) From the research objective, determine which variable is
explanatory and which variable...

Researchers conducted a study to determine whether magnets are
effective in treating back pain. The results are shown in the table
for the treatment (with magnets) group and the sham (or placebo)
group. The results are a measure of reduction in back pain. Assume
that the two samples are independent simple random samples selected
from normally distributed populations, and do not assume that the
population standard deviations are equal. Complete parts (a) and
(b) below. Use a 0.05 significance level...
