A group of students with normally distributed salaries earn an average of 6800 with a standard deviation of $2500. Find the cuto
ff for the salary that corresponds to the lower 25% of all salaries
1 answer:
Answer: $5115
Step-by-step explanation:
The following information can be gotten from the question:
Mean = 6800
Standard deviation = 2500
We will then find the Z score of the 25th percentile which will be -0.674.
Therefore, the cutoff for the salary that corresponds to the lower 25% of all salaries will be:
= 6800 - 0.674 × 2500
= 6800 - 1685
= 5115
The cutoff is $5115
