Calculate the z-score for the given data points in the item using the equation,
 
                             z-score = (x - μ) / σ
where x is the data point, μ is the mean, and σ is the standard deviation.
Substituting,
             (47.7)     z-score = (47.7 - 52.5)/2.4 = -2
This translates to a percentile of 2.28%.
              (54.9)      z-score = (54.9 - 52.5)/2.4 = 1
This translates to a percentile of 84.13%. 
Then, subtract the calculate percentiles to give us the final answer of <em>81.85%.</em> 
Thus, 81.85% of the Siberian Husky sled dogs are expected to weigh between 47.7 and 54.9 lbs.

Answer:  1.25
Step-by-step explanation:
Given: A college-entrance exam is designed so that scores are normally distributed with a mean = 500 and a standard deviation
 = 500 and a standard deviation =  100.
 =  100. 
A z-score measures how many standard deviations a given measurement deviates from the mean.
Let Y be a random variable that denotes the scores in the exam.
Formula for z-score = 
 
Z-score = 
⇒ Z-score = 
⇒Z-score =1.25
Therefore , the required z-score = 1.25
