Asked Nov 2, 2019

Assume that a procedure yields a binomial distribution with n=1222n=1222 trials and the probability of success for one trial is p=38%p=38%.

Find the mean for this binomial distribution.*(Round answer to one decimal place.)*

μ=μ=

Find the standard deviation for this distribution.*(Round answer to two decimal places.)*

σ=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 =

Step 1

It is given that the random variable *X* follows a binomial distribution with *n*=1,222 and *p*=0.38.

The mean of binomial random variable is given and calculated as follows:

Step 2
