Answer:

<em>The percentage of males are not at least 172 pounds</em>

P(X⁻ ≥ 172) = 0.26

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that 74% of 19 -year -old males are at least 172 pounds

Let 'X' be a random variable in a binomial distribution

P( X≥172) = 74% = 0.74

<em>we have to find that the percentage of males are not at least 172 pounds</em>

<u><em>Step(ii):-</em></u>

<em>The probability of males are not at least 172 pounds</em>

P(X⁻≥172) = 1- P( X≥172)

                 = 1- 0.74

<em>                  = 0.26</em>

<u><em>Final answer:-</em></u>

<em>The percentage of males are not at least 172 pounds</em>

P(X⁻ ≥ 172) = 0.26

<u><em></em></u>
