A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, x, is found to be 108, and the sample standard deviation, s, is found to be 12.
(a) Construct a 96% confidence interval about p if the sample size, n, is 27.
(b) Construct a 96% confidence interval about u if the sample size, n, is 15.
(c) Construct a 90% confidence interval about p if the sample size, n, is 27.
(d) Should the confidence intervals in parts (a)-(c) have been computed if the population had not
been normally distributed?

sine

step-by-step explanation:

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b

d

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
