Asimple random sample of size n is drawn from a population that is normally distributed. the sample mean, x overbarx, is found to be , and the sample standard deviation, s, is found to be 1010. (a) construct anan 8080% confidence interval about muμ if the sample size, n, is 1212. (b) construct anan 8080% confidence interval about muμ if the sample size, n, is 1818. (c) construct aa % confidence interval about muμ if the sample size, n, is 1212. (d) could we have computed the confidence intervals in parts () if the population had not been normally distributed? click the icon to view the table of areas under the t-distribution.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

javeir earned 56 dollors more than kyle so kyle and javier had 14w but javier made 56 dollors more so 14w plus 56 equals 70w so kyle has 14w

step-by-step explanation: hope i plz give me brainliest with the points so this is not constant cause it says last week so its clearly not every week

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
