Answer:
Since ad-hoc testing is done without any planning and in unstructured way so recreation of bugs sometime becomes a big trouble. The test scenarios executed during the ad-hoc testing are not documented so the tester has to keep all the scenarios in their mind which he/she might not be able to recollect in future.
Ad-hoc testing is done in an unplanned, unorganized manner, making it sometimes very difficult to recreate issues.
What is ad hoc?The definition of the phrase "ad hoc" is "not in order, not organized, or unstructured." In a similar vein, ad-hoc testing is nothing more than a form of behavioral or black-box testing.
Without adhering to any formal method, such as a test strategy, test cases, or requirement documentation, ad hoc testing is performed. Similarly to this, there is NO formal testing procedure that can be recorded when performing ad-hoc testing.
Ad-hoc testing is typically used to identify problems or flaws that cannot be detected through the regular approach.
Therefore, the test scenarios that are carried out during ad-hoc testing are not documented, thus the tester must keep all of the situations in mind as they may be difficult to recall in the future.

Using the data for age given in Exercise 3.3, (a) Plot an equal-width histogram of width 10. (b) Sketch examples of each of the following sampling techniques: SRSWOR, SRSWR, cluster sampling, and stratified sampling. Use samples of size 5 and the strata “youth,” “middle-aged,” and “senior.”
Using the knowledge in computational language in python it is possible to write a code that Use samples of size 5 and the strata “youth,” “middle-aged,” and “senior.”
Writting the code;{13,15,16,16,19,20,20} interval [11-20] F=7 ages
{21,22,22,25,25,25,25,25,30} interval [21-30] F=8 ages
{33,33,35,35,35,36,40} interval[31-40] F=8 ages
{45,46} interval [41-40] F=2 ages
{0} interval [51-60] F=0 age
{70} interval [61-70] F=1 age
Each unit can be chosen one time
therefore Sample size=5
{13,15,16,19,20}
repetition is allowed
Sample size=5
{13,13,13,15,16}
All units in a cluster is selected
{33,35,36,40}
Youth {16,19,20,21,22}
Middle aged {33,35,36,40,45,46}{
Senior {52,70}
Sample={16,21,33,40,52}
