Answer:
Methods of obtaining a sample of 600 employees from the 4,700 workforce:
Part A: The type of sampling method proposed by the CEO is Convenience Sampling.
Part B: When there are equal number of participants in both campuses, stratification by campus would give a more precise approximation of the proportion of employees who are satisfied with the cleanliness of the breakrooms than stratification by gender. Another method to ensure that stratification by campus gives a more precise approximation of the proportion of employees who are satisfied with the cleanliness of the breakrooms than stratification by gender is to ensure that the sample is proportional to the proportion of each campus to the whole population or workforce.
Step-by-step explanation:
A Convenience Sampling technique is a non-probability (non-random) sampling method and the participants are selected based on availability (early attendees). The early attendees might be different from the late attendees in characteristics such as age, sex, etc. Therefore, sampling biases are present. All non-probability sampling methods are prone to volunteer bias.
Stratified sampling is more accurate and representative of the population. It reduces sampling bias. The difficulty arises in choosing the characteristic to stratify by.
Total number of students = 10
As we have to find
P(A/B) = Probability( A when B has happend)
P(A/B)= P(A intersection B)/P(B)
According to given figure only yolanda and Rob are in both club
Therefore,P(A intersection B) 
Number of student in karate club =6
P(B)
P(A/B) 
Converting division into multiplication by reciprocating the term after division
P(A/B) 
On solving we get ,
P(A/B) 
P(A/B)
P(A/B) 
Answer: 6 hours
Step-by-step explanation:
Given, Tim and Jim are working on a school project together.
Tim takes 10 hours to complete the school project.
If Jim worked alone, it would take him 15 hours
Let t be the time they both take if they work together.
Then, 
So, it will take<u> 6 hours</u> to complete the school project together .
Answer:
Step-by-step explanation:
$27.63 / 2 = $13.82
$13.82 * 0.20 = $2.76
$13.82 + $2.76 = $16.58
Answer:
0.22 hour, or 13.33 minutes
Step-by-step explanation:
2/9 hour is roughly equivalent to 0.22 hour, or 13.33 minutes.
