Answer:  To remove bias when estimating the proportion of working adults living in urban, suburban, and rural areas.

Explanation: In simple words, stratification refers to the process in which different sections of the society are grouped on the basis of one or more general factors.

In the given case, the company wants to estimate the minutes of working adults in the region and the region is grouped into urban, suburban and rural.

Thus, the random selection from different regions is done so that no bias takes place regarding the number of adult working in these three different areas.

Monica [59]

Answer:

Expected cash balance = $48000

Explanation:

Given

Cash receipts = 171000

Cash disbursements = 158000

Starting period = 35000

Minimum desired cash balance = 10000

From the above,

Cash available = Cash receipts + starting period

= 171000 + 35000

= 206000

Therefore,

Cash balance at the month end

= Cash available - Cash disbursements (payments)

= 206000 - 158000

= $48000

kvv77 [185]

Leaders must be consistent in their words.

  • There are many advantages to being an ethical leader. Leaders can influence their community to act morally by working together. Others will be inspired to emulate your moral behavior if you set an example for them and offer guidance. Moral leaders can influence a large number of people for the better by presenting them with a course of action that will benefit everyone.
  • For personal credibility and reputation, it is essential to be an ethical leader. Being a leader takes time and effort. Being unethical can seriously damage a leader's or their organization's reputation and immediately remove them from the A-league.
  • A person's self-esteem is frequently harmed by unethical behavior, which leads to a less than ideal outcome and a missed opportunity to reach one's full potential.

Thus a Leader must be consistent in their words.
