The graph that shows the sampling distribution of the sample minimum age is; Option C Graph
<h3>Sampling distribution</h3>
We are given the ages of the 5 teachers as;
23, 34, 37, 42 and 58.
- The options that show the sampling distribution of the sample minimum age has been attached.
Since 4 teachers will be selected out of the 5, it means that the minimum age of the 4 selected teachers will be 23 years of age 4 time while the minimum age will be 34 if the 23 year old teacher is not selected.
- In conclusion, the sampling distribution for this scenario of minimum age should show 4 teachers at the 23 year mark and 1 teacher at the 34 year mark.

The answer to this is systematic musicology. (:
Answer:
(a) 31 , 54
(b) 48
Explanation:
- Data set : 13 13 13 20 26 29 31 33 34 34 35 35 36 37 38 41 41 41 45 45 47 47 48 52 54 56 56 62 67 82
- Part a requires you to find second decile and 8th decile
- For second decile there are 30 elements for second decile:
(a) Locator: 0.2*30 = 6
Round up to 7
20% decile = 31
Locator: 0.8*30 = 24
Round up to 25
80% decile = 54
(b) To determine 67th percentile
Locator : 0.67^30 = 20.1
Round up to 22
67% percentile = 48
