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.
Answer:
0.531 > 0.456
0.63 > 0.47
0.267 < 0.539
0.07 < 0.7
Step-by-step explanation:
a. 0.531 _____ 0.456
compare the numbers from left to right
5 is greater than 4 so 0.531 greater than 0.456
0.531 > 0.456
b. 0.63 _____ 0.47
6 is greater than 4. 0.63 > 0.47
c. 0.267 _____ 0.539
2 is less than 5 . so 0.267 less than 0.539
0.267 < 0.539
d. 0.07 _____ 0.7
0 is less than 7
0.07 < 0.7

Step-by-step explanation:
Break even point is where all the expense is already covered by the revenue. In this case, the expense would be the stand ($75,000) and the lemon+sugar+water ( $1.25 per glass). The revenue comes from lemonade($30/glass). Then the equation would be:
$30 * glass of lemonade= $75,000 + $1.25 * glass of lemonade
($30-$1.25) * glass of lemonade= $75,000
glass of lemonade= 2608.7
Step-by-step explanation:
0.6/100= 0.006 should be multiplied to decrease by 0.6%
