Hello students, for this question first we need to arrange the data in ascending order 57, 58, 58, 59, 60, 62, 62, 62, 62, 63, 63, 64, 64, 65 and 78.
00:22
Here the number of values are 15.
00:24
First we need to calculate the quartile 1, the q1 which is equal to n plus 1 divided by the fourth value which is here 16 by 4 is equal to the fourth value.
00:45
The fourth value is equal to 59.
00:49
Our q1 is equal to 51 and then we need to find the q2 which is n plus 1 divided by the 2th value that is equal to 8th value is equal to 62.
01:06
Then q3 which is 3 into n plus 1 divided by 4th value that is 3 into 4 that means the 12th value which is equal to 64.
01:18
And also here for the subpart v we need to find the interquartile range iqr which is q3 minus q1.
01:30
Now here 64 minus 59 we get our interquartile range is equal to 5.
01:39
Then we have to find the outlier for the given question...
