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.

• =1,000=1,000FTES
• median=1,014=1,014FTES
• =474=474FTES
• first quartile=528.5=528.5FTES
• third quartile=1,447.5=1,447.5FTES
• n=29n=29years

(a) A sample of 1515 years is taken. How many are expected to have a FTES of 1,0141,014 or above?

(b)75%75% of all years have an FTES:

(i) at or below
