4. (a) suppose x has a normal distribution with mean u= 18 and standard
deviation = 13. if you draw random samples of size 5 from the x
distribution and represents the sample mean, what can you say about the
x distribution ? how could you standardize the x distribution?

Determine whether the samples are independent or dependent. upper a data set includes the morning and evening temperature for the lasta data set includes the morning and evening temperature for the last 90 days.90 days.

Non-euclidean geometry was discovered when, in seeking cleaner alternatives to the fifth postulate, it was found that the negation could also be true a. true b. false
