The number is students
Step-by-step explanation:
From the question we are told that
The population mean is
The standard deviation is
The sample size is n = 2000
percentage of the would you expect to have a score between 250 and 305 is mathematically represented as
Generally
So
From the z table the value of
and
The percentage is
The number of students that will get this score is
1/5k+ 15
= 1/5k+ 15* (5/5) (because 5/5= 1)
= 1/5k+ (15*5)/ 5
= 1/5k+ 75/5
= 1/5k+ 75* (1/5)
= 1/5(k+ 75) (distributive property)
The final answer is 1/5(k+ 75).
