Past experience has indicated that the breaking strength of yarn used in manufacturing drapery material is normally distributed with a standard deviation of 3 psi. A random sample of 9 specimens is tested, and the average breaking strength is found to be 97 psi. a) Find a 95% two-sided confidence interval on the true mean breaking strength. b) Find a 95% lower bound confidence interval on the true mean breaking strength.

//blooming serenity//

beautiful in the morning

mysterious at night

wonderous nature souring

with all it's mystical might

the flower that blooms

to the fox that looms

nocturnal creatures

with various features

a blooming flower soon in sight

as a new little hatchling fears to take flight  

afraid to leave it's calming nest,

but dear little bird, mother knows best

as sure as there are stars in the sky,

life is not about who, where what, when or why-

it's the journey that follows

adventures we swallow

of   nature's deep wonders,

natural disasters and storm's thunders.

blooming serenity

life and nature, truly is heavenly.
