State the domain and range of each relation. Then determine whether each relation is a function. Write yes or no.
Step 1 of 3
Z SCORES AND TABLE NOTES AND PRACTICE Z-Scores -measure of how many standard deviations there are between a data value and the mean Z= x-μ(mean of population) / σ (standard deviation) EX; $247 skis Mean $279 SD= $16 Z= 247279 /16 Z=2 The price of the skis are 2 standard deviations below the mean ZTable used to find the proportion that falls to the left of the mean Ex: find the proportion when the z score is less that 2.47 =.9932 99.32 percent of the data was 2.47 standard deviations away Ex: find the proportion where z is greater than 1.53 1.937=.063 6.3% of the data is greater than 1.53 sd's away Average Hrs sleep= 6 hrs Sd=1.3 A) z=-1.6, how many hours -1.6= (x-6) / 1.3 3.92
