Question

A local poll found that only 17% of the 546 people surveyed feel the mayor's new city tax plan is effective. Find the mean of this binomial distribution

Answer 1

Answer-

The mean of this binomial distribution was found to be 92.82

Solution-

The distribution is given as Binomial distribution.

In binomial distribution the mean is calculated as,

$\mu_{x}=n\cdot p$

where

n = number of trials = 546

p = probability of success = 17% = 0.17

Putting the values,

$\mu_{x}=546\times 0.17=92.82$

Therefore, the mean of this binomial distribution is 92.82
