Given:
There are given the statement, "66% of nineteen-year-old males are at least 143 pounds".
Explanation:
According to the question:
We need to find their complement.
So,
The completement statement is:
"66% of nineteen-year-old males are not at least 143 pounds"
Then,
The probability that 66% of nineteen-year-old males are at least 143 pounds is:
[tex]P_1=0.66[/tex]
So,
The complement is:
[tex]P_c=1-P_1[/tex]
So,
[tex]\begin{gathered} P_{c}=1-P_{1} \\ P_c=1-0.66 \\ P_c=0.34 \\ P_c=34\% \end{gathered}[/tex]
Final answer:
Hence, the percentage of completion of the given statement is shown below:
[tex]34\%[/tex]
