A particular leg bone for dinosaur fossils has a mean length of 60 inches with a standard deviation of 3 inches. What is the len
stepan [7]

The average length of a specific dinosaur leg bone is 60 inches, with a standard variation of 3 inches. If a z-score is 0, then the length is 67.

Divide your data point by your standard error after taking your data point and subtracting the mean from it. How is the z-score determined? Z-scores are calculated using the formula z = (x-)/, where x represents the raw score, the population mean, & the population variation. The z-score is just the raw score less the population mean, split by the population variance, as the calculation demonstrates. You now have your Z-score. For instance, a scoring of 450 would equate a scores of (450-500)/100 (= -50/100 = -0.50 on a scale with a mean of 500 as well as a standard variation of 100, indicating that the scoring is half a variance below the mean.

50% chance of the offspring being heterozygous dominant (Tt)
