Problem P2.16

File names and extensions. Write a program that prompts the user for the drive letter(C), the path (\Windows\System), the file name (Readme), and the extension (txt). Thenprint the complete file name C:\Windows\System\Readme.txt. (If you use UNIX or aMacintosh, skip the drive name and use / instead of \ to separate directories.)

Step 1 of 3

MODULE 4 ARTICLE I. INFERENCE FOR POPULATION MEANS 1) Confidence Intervals a. We can find confidence intervals of two differencesample means 2) Known Population Variances a. Let X and Y be to independent binomial random variables. b. A 100(1-α)% CI for the difference of the two meansfrom each random variable is: 3) Unknown population variance a. t-value is used 4) Large sample confidence intervals for two population proportions a. Let X and Y be to independent binomial random variables. b. Proportion p is the number of successes/n ̃ c. Let n =nx+2x d. Let p =(x+1)/ n x e. The CI is therefore: Note: the difference of two proportions should liebetween -1 and 1 5) Paired Data a. There are instances when two samples are not independent, this is when the data is paired. b. It is referred to as paired because we consider thedata in pairs, (X ,Y ) 1 1 c. We use the data set of differences, D =X -Y fo1 ca1cul1tion i. This reduces a 2 sample problem to a 1 sample problem d. This holds equivalently for the means of two separate samples e. NOTE: differences (D) can be incorporated into covariance by:
