A health care provider was reviewing test scores from the Beck Anxiety scale (scores can range from 0 to 63). What is the probability of selecting a random sample of 200 individuals in a population who score a mean of 50 or higher on the Beck Anxiety scale given that the population mean (µ) is 48 and the standard deviation is six.
A pre-physical therapy student took the Graduate Record Exam (GRE) for admission to a PT program. The range of scores is 130 to 170 for each of the two sections (verbal and quantitative). What is the probability of selecting a random sample of 350 pre-PT students (they indicate this on the exam) who scored a mean of 140 or higher. For the verbal section, the population mean (µ) is 132 with standard deviation of 7. For the quantitative section, the population mean (µ) is 134 with standard deviation of nine.
