Statistic R Question. Can anyone show R step by step?
Thank you!
Problem 1. Refer to Kimberly-Clark Corporation's survey of 250 people who kept a count of their use of Kleenex® tissues in diaries. We want to test the claim made by marketing experts that -60 is the average number of tissues used by people with colds against our belief that the population mean is smaller than 60 tissues. We will select = 0.05 as the level of significance for the test. The survey results for the 250 sampled KleenexR users are in the tissues.txt data file. Data are available at tissues_url-"http://www.math.unm.edu/"alvaro/tissues.txt" Please do the following a) Assign the values from the variable NUMUSED to an object (vector) that bears your family name Example tissues_url-"http://www.math.unm.edu/"alvaro/tissues.txt" tissues_data read.table(tissues_url,header-TRUE); blackwell = tissues-data$NUMUSED; b) Using R, conduct a test at 5% significance level c) State your conclusion in the context of this problem Put your answers to parts a) c) in a word document that fits on one sheet of paper. At the top of the page, put your name and student number. Title the page Tissues Data (Mean). Copy-and-paste your commands and the responses from the session window to the word document.Explanation / Answer
