Astudent measures the gravitational acceleration g to be 9.76±0.07 m/s2. to improve his precision he spend a whole day repeating the measurement 400 times. he states the mean of the 400 measurements g 9.746 m/s2 as his best estimate of g. in the lab g has an accepted value of g- 9.80664 t0.2 m/s2 arising from a precision measurement conducted by geo-physicists in the past.

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.
