Compute the interquartile range (use formula/process in question #4 to compute the percentiles)This is what my question 4 was…(For the scores 4, 6, 9, 10, 13, 15, 17, 19, 20, and 22, calculate the 45th percentile using the formula: R = P/100 * (N+1) to compute the rank first, then the percentile (Method 3, in Lane Text). Okay so i just need help understanding the question. With this question i was given numbers such as 22.5,18.4,19.0,25.6,23.6,24.0,48.5,22.4,25.0,18.1 And was asked to find the mean median and variance which i did which was.. 24.71 (mean) 23.05 (median) 71.21 (variance) Now when I think of this question I think its asking me to find the IQR which is Q3-Q1 and when i do that I have Q1=19 Q3=25 25-19 = 6 (IQR) But I am not sure that is what he is asking me because he says percentiles so I am not sure if I am just supposed to look up the 65 percentile like I did for question 4 or if i should find the percentiles for 25,50,75. It is really unclear and i am confused any help in the right direction would be great.
