Aparticularly statistically curious clickbait website writer noticed that all the cool creative people he knows are also very anxious or neurotic. To test his hunch, he find 5 volunteer friendsand gives thema surveyon neuroticism (1-5 point scale) and a puzzle he found on the internet that supposedly is solved faster by more creative peopleand measures how long it takes each person to solve in seconds. The data areXneuroticism: 3.6, 1.5, 2.85, 2, 4.9Xcreativity: 32, 62, 123, 15, 4 A. Identify the appropriate statistical measure to use. B. Conduct the test. Make a decision about the null hypothesis, interpret your results and calculate effect size if applicable. At ?=.05,is the writer right about his hunch?

The Z-score tells you the number of standard deviations away from the mean (and in what direction) a data value is. The formula: Z = *- can be used to find the Z-score for a single member of the population. Notice X - μ tells you the signed distance the data value (X) is from the mean. When you divide that by the size of each chunk (the standard deviation) you are measuring the distance in units of the size of the standard deviations (how many standard deviations fit in the distance between the data value and the mean) - which gives you the Z-score. The formula X = μ+Z.o can be used to find the value in the population when given the Z-score (signed number of standard deviations). Notice that Z. tells you how far from the mean the data value is (since Z is the number of standard deviations and is the size of each standard deviation the product tells the total distance). So adding the distance from the mean to the mean gives the location along the number line for the data value. A…
