Polymer composite materials have gained popularity because they have high strength to weight ratios and are relatively easy and inexpensive to manufacture. however, their nondegradable nature has prompted development of environmentally friendly composites using natural materials. an article reported that for a sample of 10 specimens with 2% fiber content, the sample mean tensile strength (mpa) was 51.9 and the sample standard deviation was 1.2. suppose the true average strength for 0% fibers (pure cellulose) is known to be 48 mpa. does the data provide compelling evidence for concluding that true average strength for the wsf/cellulose composite exceeds this value? (use α = 0.05.)

the answer would be c:   ax + b = ax + c

//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.
