Answer 1

In this case, we need to check whether the result has statistical and practical significance or not.

Statistical Significance:

In the study, when the result obtained is very unlikely to occur just by chance alone, then statistical significance is achieved. The general criterion for statistical significance is the likelihood of occurring of an event just by chance is 5% or less. When a treatment is tested, the statistical significance gives the conclusion how the treatment is unlikely to be effective just by chance alone.

In the procedure, it is mentioned that there would be 19% chance of happening that a baby girl would be born from the members who used the method. This implies that giving birth to a baby girl is not very unlikely to occur just by chance alone. Also, 19% is greater than general criterion for statistical significance of 5%.

Thus, the result does not appear to have statistical significance.

Practical Significance:

The results have a Practical Significance if the difference is not very small and thus that the differene is large enough to justify its use.

The Difference between the No. of Girls and Boys = 1020 - 980 = 40

This Difference is Very small among the total users of 2000 i.e. (40/2000)*100 = 2%

Thus the Results also do not have Practical Significance.
