Answer:
The percentage of males are not at least 172 pounds
P(X⁻ ≥ 172) = 0.26
Step-by-step explanation:
Step(i):-
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
we have to find that the percentage of males are not at least 172 pounds
Step(ii):-
The probability of males are not at least 172 pounds
P(X⁻≥172) = 1- P( X≥172)
= 1- 0.74
= 0.26
Final answer:-
The percentage of males are not at least 172 pounds
P(X⁻ ≥ 172) = 0.26
