Consider a sample with data values of 10, 20, 12, 17, and 16. Compute the z-score for each of the five observations (to 2 decimals). Observed value z-score 10 20 12 17 16

mean = (10+20+12+17+16)/5=15 standard deviation = 4 (based on the data) Z-score = (X-mean)/standard deviation Observed Value Z-score 10 (10-15)/4 =-1.25 20 (20-15)/4=1.25 12 (12-15)/4=-0.75 17 (17-15)/4=0.5 16 (16-15)/4=0.25 More test answers on https://studyhippo.com/ba275-assignment-1/

Ratios in Simplest Form (Decimals)

Decimals in ratios: divide the numerator by the denominator to get a decimal. Hit 2nd PRB to change it to a fraction. If you get a mixed numeral, hit 2nd Ab/c to change it to an improper fraction (because there should be no mixed numbers in ratios) More test answers on https://studyhippo.com/math-chapter-5-6/
