Aprogram is seeded with 30 faults. during testing, 21 faults are detected, 15 of which are seeded faults and 6 of which are indigenous faults. what is the mill's estimate of the number of indigenous faults remaining undetected in the program?

Estimated number of indigenous faults remaining undetected is 6

Explanation:

The maximum likelihood estimate of indigenous faults is given by,

here,

= the number of unseeded faults = 6

= number of seeded faults = 30

= number of seeded faults found = 15

So NF will be calculated as,

And the estimate of faults remaining is   = 12 - 6 = 6

To make a box and whisker plot you must first order the data:

11, 13, 16, 18, 21, 23, 24, 29

Then find the median:

19.5

Then split the data into two sections by the median:

11, 13, 16, 18 and 21, 23, 24, 29

Now find the medians of those sets

14.5 and 23.5

With this information we can conclude Option C is the correct plot

Hope this helps!
