Sixty-two percent of adults in a certain country believe that life on other planets is plausible. You randomly select five adults and ask them whether they believe that life on other
planets is plausible. The random variable represents the number of adults who believe that life on other planets is plausible. Find the mean, variance, and standard deviation of the
binomial distribution for the random variable. Interpret the results.

Interpret the results.
On average, out of every 5 adults in the country believe that life on other planets is plausible. In most samples of 5 adults, the number of adults who think life on other planets is
plausible would differ from the mean by no more than

Expert Solution
Step 1
Given that
n = 5 , p = 62% = 0.62 , q = 1 - p = 1 - 0.62 = 0.38
X ~ Binomial ( n = 5 , p = 0.62 )
p = Probability of adults in a certain country believe that life on other planets is plausible
X = Number of adults in a certain country believe that life on other planets is plausible.
