The three confidence intervals in SCRAMBLED order are as follows: (i) (.229, .488) (ii) (.250, .467) (iii) (.189, .528) What are the confidence levels of each of the above confidence intervals? (a) (i) 99% (1i) 95% (iii) 90% (b) (i) 99% (1i) 90% (iii) 95% (c) (1) 90% (1i) 99% (iii) 95% (d) (1) 95% (1i) 99% (1ii) 90% (e) (1) 95% (ii) 90% (iii) 99%
