Expected number of admissions

(2) Compute the varianceand the standard deviationof the number of admissions. (Round your answers to 2 decimal places.)

Variance

Standard deviation

1) Expected number of admissions = E(x) = x * p(x) = 1070(0.3) …

The Solution provides the expected number of admissions, Variance and Standard deviation.
