J. [-I 2 PoInts] DETAILS MY NOTES SCAL Use De Moivre's Theorem with \( n=3 \) to express \( \cos (3 \theta) \) ar \( \cos (3 \theta)=\square \) \( \sin (3 \theta)=\square \)

Una muestra aleatoria de tamaño \( \boldsymbol{n}_{1}=\mathbf{2 5} \) que se toma de una población normal con una desviación estándar \( \boldsymbol{\sigma}_{1}=5 \) tiene una media \( \overline{\boldsymbol{x}}_{1}=\mathbf{8 0} \). Una segunda muestra aleatoria de tamaño \( \mathbf{n}_{2}=\mathbf{3 6} \), tomada de una población normal diferente con una des- viación estándar \( \boldsymbol{\sigma}_{2}=\mathbf{3} \), tiene una media \( \overline{\boldsymbol{x}}_{2}=\mathbf{7 5} \). Encuentre un intervalo de confianza del \( \mathbf{9 4 \%} \% \) para \( \boldsymbol{\mu}_{1}-\boldsymbol{\mu}_{2} \).
