The length of this gestation period was shorter than the mean length of gestation periods by 1.7 standard deviations.
Step-by-step explanation:
Mathematically, to obtain the z-score, we use the following formula;
z-score = (x-mean)/SD
The z-score obtained can either be positive or negative. When z-score obtained is positive, it shows that the given value is bigger than the mean. In cases where z-score is negative, it means that the value we are calculating is smaller than the mean.
In the given formula, the value x represents the value which we are comparing against the mean value.

<span>So we wan't to know what is the sum of 3 2/3 and 14 2/5. First lets turn them into fractions: first one is 11/3 and the second is 72/5. Now lets add them: We multiply fractions this way: (a/b)+(c/d)={(a*d)+(c*b)}/(b*d). Following this rule: {(11*5)+(72*3)}/(3*5)={55+146}/15=201/15. and finally lets turn it back into a mixed number: 13 6/15</span>
