A teacher says that the top 14% of the class received an A on the last test. The scores were normally distributed with mean 70
1 answer:
Answer: The minimum score would be 83.08.
Step-by-step explanation:
Since we have given that
Mean = 70
Standard deviation = 12
Top 14% of the class received an A on last test.
So, right tail of (100-14=86%) = 1.09
So, the minimum score required to get an A is given by
Hence, the minimum score would be 83.08.
