Q Question 1 2 / 2 pts A population of scores has µ = 44. In this population, a score of X = 40 corresponds to z = –1.00. What is the population standard deviation? Question 2 2 / 2 pts Using z-scores, a population with µ = 37 and ? = 6 is standardized so that the new mean is µ = 50 and ? = 10. After the standardization, one individual has a score of X = 55. What was this individual’s score in the original distribution? Question 3 2 / 2 pts A z-score indicates the distance in standard deviations a score (X) falls above or below the mean of a distribution. Correct! Question 4 2 / 2 pts Which z-score corresponds to a score that is above the mean by 2 standard deviations? Question 5 0 / 2 pts A researcher is interested in examining whether self-affirming oneself leads to decreased anxiety in response to threatening information. The researcher conducts a research study in which an individual is self-affirmed prior to receiving threatening information. Researchers know that on average individuals tend to have anxiety levels of µ = 10 with a standard deviation of ? = 2 when presented with this threatening information. If a self-affirmed individual has an anxiety level of X = 5 following the threatening message, it is reasonable to conclude that self-affirmation ______.
