Step by step solution

01

Given Information

A business needs to assess its attrition, or the length of time new employees stay with the organisation. They've developed a comprehensive confidence interval over time.

02

Concept Information

Now let us call the lot of years a new recruit will stay with the company and the probability that a new hire will stay with the company years P(X).

Only when, according to discrete distributed features, is perhaps the probability functional of a continuous variable X.

i. P(X)≥0for all X

ii. ∑P(X)=1

03

Calculation

The missing percentage can be calculated using condition (ii) as follows:

∑P(X)=0.12+0.18+0.30+0.15+PX4+0.10+0.05=1

localid="1648917609114" PX4=1-0.90

=0.10

04

Conclusion

As a result, the table's missing value is 0.10.
