Assume that a procedure yields a binomial distribution with n= 136 trials and the probability of success for one trial is p = 56%. Find the mean for this binomial distribution. (Round answer to one decimial place) μ = ------------- Find the standard deviation for this distribution. (round answer to two decimal places) σ = Use the range rule of thumb to find the minimum usual value μ-2σ and the maximum usual value μ+2σ. Enter answer as an interval using square- brackets ONLY WITH WHOLE NUMBERS. usual values = [ ]
(1) Assume that a procedure yields a binomial distribution with n= 136 trials and the probability of success for one trial is p = 56%.
Find the mean for this binomial distribution. (Round answer to one decimial place)
μ = -------------
Find the standard deviation for this distribution. (round answer to two decimal places)
σ =
Use the
usual values = [ ]
(2) The age of children in kindergaten on the first day of school is uniformly distributed 4.75 and 5.82 years old. A first toime kindergarten child is selected at random. Round answers to 4 decimal places if possible.
