Can you help me solve this using R? 2. Recall the Going Wireless data first mentioned Week 2 of this class. The article Going Wireless (AARP Bulletin, June 2009) reported the estimated percentage of house- holds with only wireless phone service (no land line) for the 50 U.S. states and the District of Columbia. In the accompanying data table, each state was also classified into one of three geographical regions—West (W), Middle states (M), and East (E). Consider only the variable `Wireless` in this data. ```{r} wireless.data <- read.csv("https://goo.gl/72BKSf", header = TRUE) str(wireless.data) ``` i) Compute the mean and standard deviation of the wireless data above. Describe the sample using these summaries. ii) Create a histogram and QQ-plot of the wireless data. Is the normality assumption reasonable? iii) Use the data to estimate the mean wireless percentage per state using a 90\% confidence interval. Provide an interpretation of this interval. iv) Use the data to test the hypothesis that the mean wireless percentage per state is less than 17. Use alpha = 0.05 (5\%) level of significance.
