A researcher has found that pilots taking an over the counter antihistamine have poor reaction times. They performed an experiment on 22 pilots: 11 took the medication and 11 did not. Their reaction times to a command by Air Traffic Control was considered to be adequate or inadequate. Among those taking the medication, 8 were rated inadequate and 3 adequate. Among those not-taking the medication, 10 were rated adequate and only 1 inadequate. Construct a contingency table. Run the Chi-Square test for independence using the calculator in the module. Note that StatCrunch does NOT support this type of Chi-Square • State your findings and their significance. Do not forget to give summary statistics in APA format.
• What is the problem with this research study? Is the Chi-Square test appropriate? Why or why not? What could the researcher do to potentially rectify the problem?

A researcher would like to determine whether an
over-the-counter herbal nasal spray has an effect on mental
alertness for infants. A sample of n = 18 infants is obtained, and
each baby is given a standard dose of the spray one hour before
being tested for mental alertness. For the general population of
infants, scores on a mental alertness screening test are normally
distributed with μ = 60. The infants in the sample had an average
score of M =...

A nurse is caring for a patient taking three over-the-counter
medications for pain and insomnia. The primary care provider has
prescribed a generic drug for the patient for asthma. The patient
requests information from the nurse about over-the-counter
medications and the difference between generic and brand-name
drugs.
Although over-the-counter drugs have been found to be safe when
taken as directed, what should the nurse consider telling the
patient about problems related to over-the-counter drugs?

Recall the researcher who investigated the relationship between
hours of sleep and reaction times in the Week 4 Application. As a
follow up to that study, the researcher wants to conduct a
correlation to investigate further if there is a relationship
between hours of sleep and reaction time. For this experiment,
participants are allowed to sleep as much as they would like (that
is, they are not assigned to sleep any specific number of hours).
When 20 participants come to...
