Answer:
69.23% probability that a person is not qualified if he or she was not approved by the manager.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes:
In this problem, we have these following probabilities:
80% probability that a person is qualified
20% probability that a person is not qualified.
90% probability that a qualified person is approved.
10% probability that a qualified person is not approved.
10% probability that an unqualified person is approved.
90% probability that an unqualified person is not approved.
Find the probability that a person is not qualified if he or she was not approved by the manager.
Desired outcomes
Unqualified and not approved.
20% are not qualified. Of those, 90% were not approved. So
Total outcomes:
Qualified and not approved or unqualified and not approved.
80% are qualified. Of those, 10% were not approved
20% are not qualified. Of those, 90% were not approved. So
Probability
69.23% probability that a person is not qualified if he or she was not approved by the manager.
Answer:
20
Step-by-step explanation:
Given that:
The study group n = 4
number of participants = 10
the sum of squares for the between-groups source of variation is 60
The objective is to determine the mean square between groups in this study
The mean square between groups in this study compares the means of the group with the sum of squares for the between-groups source (i.e the grand mean)
For this analysis;
the degree of freedom = n-1
the degree of freedom = 4 - 1
the degree of freedom = 3
Thus; the mean square between groups =
the mean square between groups = 20
