Astronomy: Earths Rotation Changes in the earths rotation are exceedingly small. However, a very long-term trend could be important. (Reference: Journal of Astronomy, Vol. 57, pp. 125146.) Let I represent an increase and D a decrease in the rate of the earths rotation. The following sequence represents historical increases and decreases measured every consecutive fifth year. DDDDD I I I DDDDD I I I I I I I I I IDI I I I I Test the sequence for randomness. Use a 0.05.

Chapter 2 Notes • Deviation—Given a value y and a data point x then x-‐y represents how far x deviates from y. o Ex. Given x=10 and y=5. 10 deviates by 5 from 5. • Bar Charts—Display where the length of a bar corresponds...
