Let X1,..., X be an independent trials process for which the variance of each individual random variable is known to be less than or equal to 0.64. This means that the standard deviation σ is less than or equal to (give an answer to two decimal digits) Using this information, how many trials n are needed so that the 68% confidence interval (d = 1) for the actual mean has a length that is less than 0.91? (round up to the next highest integer)
