Consider the following information: sample mean (m) = 95 population mean (µ) = 100 population standard deviation (σ) = 18 sample size (n) = 144 based on this information, what is the lower endpoint (denoted mlower in the textbook) for the corresponding 95% confidence interval? include two decimal places when reporting your answer.

This is different from the first one can someone me

[10 points, algebra 2]according to my answer key the restrictions are -1 and 4. but why not positive 1?

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
