Two estimates are available for the same population paramete

Two estimates are available for the same population parameter. Estimate one has a standard deviation of 2.6 and estimate two has a standard deviation of 2.65. Which estimate would you choose and why? What other things must be taken into consideration?

Solution

while we are find the probability of an event it is recommended to be very precise and accurate as it will help in the

probability. so to be accurate i will chose standard deviation to be 2.65

other things that should be taken care of are varience, standard error while doint the experiment
