(B) We know that 75% of data values above first quartile.
First quartile for life science data is Q1 = 2.000
Hence, Approximately 75% of the students in Life Sciences (ls) spend more than 2.000 hours studying per day.
(C) Middle 50% of data is found between first quartile and third quartile
For biology data set, first quartile is 2.500 and third quartile is 5.000
hence, Approximately half of the students in biology (bio) study between _____2.500_____ and ___5.000_______ hours per day
