Hospital administrators at a local hospital are interested in quality of care. As such, they ask a random sample of patients that have used the hospital's health care services to fill out a questionnaire. The questionnaire has questions about the patient's worry (negative, positive), the hospital staff's communication skills (low, medium, high), and satisfaction with medical care. The administrators are interested in how patient's worry and their assessment of the hospital staff's communication impact their satisfaction with medical care. The...

A
project based on touch therapy is presented at a science fair by a
local high school student. In the study practitioners of touch
therapy are blindfolded to see if they can detect a human energy
field (HEF) without touching patients. The student believes that a
practitioners years of experience predicts the number of correct
choices to detect HEF. What can be concluded with an a=0.01?

A team of comparative psychologists are interested in the maternal behavior or rats. In an experiment, 10, 20, and 30 day-old rat pups were separated from their mothers. They then recorded the time (in seconds) required for the mother rats to retrieve the pups. The psychologists were interest in whether retrieval time varies with age. The data are given below. What can be concluded with an α of 0.05? 10 days old 20 days old 30 days old 16 11...

A high school teacher hypothesizes a negative relationship between performance in exams and performance in presentations. To examine this, the teacher computes a correlation of -0.62 from a random sample of 30 students from class. What can the teacher conclude with an α of 0.01? a) Compute the appropriate test statistic(s) to make a decision about H0.

Researchers want to know if there is a difference in learning self-care skills between two techniques. For 4 months the researchers worked with mentally impaired individuals in which half were taught self-care skills through imitation and the other half through physically guided practice. At the end of the 4 months individuals were asked to independently perform the self-care task and were rated on the level of required assistance where a higher score means more assistance. What can the researchers conclude...
