Question

The probability that you will win a game is π=0.38.

If you play the game 617 times, what is the most likely number of wins?
(Round answer to one decimal place.)
μ = 

Let XX represent the number of games (out of 617) that you win. Find the standard deviation for the probability distribution of XX.
(Round answer to two decimal places.)
σ = 

The range rule of thumb specifies that the minimum usual value for a random variable is μ–2σ and the maximum usual value is μ+2σ. You already found μ and σσ for the random variable X.


Use the range rule of thumb to find the usual range of X values. Enter answer as an interval using square-brackets and only whole numbers.
usual values =
