3 AnswersMathematics3 years agoI need some help with Statistics/Probability. Help!?
The population parameters below describe the full-time equivalent number of students (FTES) each year at Lake Tahoe Community College from 1976–1977 through 2004–2005.
• μ = 1000 FTES
• median = 1,014 FTES
• σ = 474 FTES
• first quartile = 528.5 FTES
• third quartile = 1,447.5 FTES
• n = 29 years
A sample of 11 years is taken. About how many are expected to have a FTES of 1014 or above? Explain how you determined your answer.
***NOTE: I don't quite get what I am supposed to do...so far I guess calculated the IQR which is 919 FTES. After that, I am lost.
