No, the work is correct, but the interpretation is not. “6 is less than or equal to h<span>” means that h is greater than or equal to 6. He must grow at least 6 inches, not at most 6 inches.</span>
Answer:
Answer: 78 and 82.
Step-by-step explanation:
We have been given that the average test score of the class was an 80 and the standard deviation was 2. We are asked to find two values between which 68% of class will score.
We know that in a normal distribution approximately 68% of the data falls within one standard deviation of the mean.
So 68% scores will lie within one standard deviation below and above mean that is
Upon substituting our given values, we will get
Therefore, about 68% of the class would score between 78 and 81 and option B is the correct choice.
Step-by-step explanation: Hope this helps :D
