Answer:

The correct answer is A. ~2.27

Step-by-step explanation:

1. Let's review the information given to answer the question correctly:

Mean of the weight of newborns of s particular species of rhino = 65 pounds

Standard deviation = 11

Weight of the newborn we want to calculate its z-score = 90 pounds

2. Let's calculate the value of z-score, using the following formula:

z-score = (Weight of the newborn - Mean of the weight of newborns of s particular species of rhino)/Standard deviation

Replacing with the real values, we have:

z-score = 90 - 65/11 = 25/11 = 2.272727....

z-score = 2.27 (Rounding to the nearest hundredth)
