Aresearcher administers a treatment to a sample of participants selected from a population with µ = 80. if a hypothesis test is used to evaluate the effect of the treatment, which combination of factors is most likely to result in rejecting the null hypothesis?

a. a sample mean near 80 with a=.05b. a sample mean much different than 80 with a=.05c. a sample mean much different than 80 with a=.01d. a sample mean near 80 with a=.01

answer: d. $20

step-by-step explanation:

just took the test

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

mean, 40.6

step-by-step explanation:

x = 3 ± √(5+y)
