Homework Answers
Ans)10) b) 66%
Explaination:
34.13% of the area is between the mean and +1 or -1SD units, called a z score. Therefore atotal of 68.26% (34.13% x 2) of the test scores fall between +1 and -1 SD.
11)c) cicardian variation
Explaination:
cardian variation: A circadian rhythm is a natural, internal process that regulates the sleep-wake cycle and repeats roughly every 24 hours. These 24-hour rhythms are driven by a circadian clock, and they have been widely observed in plants, animals, fungi, and cyanobacteria
