Date are drawn from a bell-shape distribution with a mean of 170 and a standard deviation of 5. There are 1700 observations in t
1 answer:
Answer:
97.73%
Step-by-step explanation:
Mean (μ) = 170
Standard deviation (σ) = 5
Assuming a normal distribution, for any observed value, X, the z-score is determined by:
For X = 180:
A z-score of 2 corresponds to the 97.73-th percentile of a normal distribution.
Therefore, the percentage of data that is less than 180 is 97.73%.

Answer:
-3
Explanation:
= -3
So first make the improper fraction into a mixed number by taking out all the whole numbers from the numerator (3) and making sure the proper sign is in front of the answer (- 3) your remainder is the original numerator minus the product of the answer times the denominator: 24 - (3 • 7) = 24 - 21 = 3. Rewrite the mixed number.
