Suppose that you are testing the hypotheses H0: muequals18 vs. HA: mugreater than18. A sample of size 16 results in a sample mean of 18.5 and a sample standard deviation of 2.3. a) What is the standard error of the mean? b) What is the critical value of t* for a 90% confidence interval? c) Construct a 90% confidence interval for mu. d) Based on the confidence interval, at alphaequals0.05 can you reject H0? Explain. a) The standard error of the mean is nothing. (Type an integer or a decimal.)

answer: i believe c. is the answer sorry if i am wrong

step-by-step explanation:

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
