The state and local police departments are trying to analyze crime rates so they can shift their patrols from decreasing-rate ar

eas to areas where rates are increasing. The city and county have been geographically segmented into areas containing 5,250 residences. The police recognize that not all crimes and offenses are reported: People do not want to become involved, consider the offenses too small to report, are too embarrassed to make a police report, or do not take the time, among other reasons. Every month, because of this, the police are contacting by phone a random sample of 1,000 of the 5,250 residences for data on crime.
(Respondents are guaranteed anonymity.) Here are the data collected for the past 12 monthsfor one area:
Construct a p-chart for 95 percent confidence (1.96) and plot each of the months. If the next three months show crime incidences in this area as
January =10 (out of 1,000 sampled)
February = 1 2 (out of 1,000 sampled)
March = 11 (out of 1,000 sampled)
What comments can you make regarding the crime rate?

Answer:

= 0.008

Explanation:

Base on the scenario been described in the question , to develop a p-chart, first calculate as shown below:

P bar= total number of defective units from all samples /(number of samples ×sample size)

= 100/(12×1000)

= 100/12000

= 0.008

Thus, the p bar is 0.008

At the end of the fiscal year, the usual adjusting entry to update Prepaid Rent for the portion of the benefit that was used up
TEA [102]

Answer:

d. net income for the year will be overstated.

Explanation:

The prepaid rent account is used to record the amount paid in advance for rent. Once the amount is paid, the entries required are

Debit Prepaid rent

Credit Cash account

On subsequent use of the rent, the required entries are

Debit Rent expense

Credit Prepaid rent

As such where at the end of the fiscal year, the usual adjusting entry to update Prepaid Rent for the portion of the benefit that was used up / expired was accidentally omitted, net income for the year will be overstated as the rent expense that would have been posted to reduce it would have been omitted.

Brut [27]
<span>Ups devices typically have capacities that may run up to  1000 va.

UPS (uninterrupted power supply) is designed so an electrical equipment could still provide an emergency source of power in case the main power input fails to do so. In order to fulfill this function, a UPS device requires a pretty high voltage capacity.</span>

If Dirk’s Doughnuts is a perfectly competitive firm and is currently incurring economic losses of $500: a. firms will enter the
GenaCL600 [577]

Answer:

The correct answer is option e.

Explanation:

In a perfectly competitive market, there are no limitations on the entry and exit of firms. If the existing firms have positive economic profits, this attracts other potential firms to join the market. In case of losses the firms incurring losses exit the market.  

If Dirk’s Doughnuts is operating in a perfectly competitive market and is incurring economic losses, firms having losses will exit the market.  

This will cause the market supply to decrease. As the supply curve shifts to the left, the price of the product will increase. This will cause profits to increase. The firms will operate at zero economic profits.

You need to accumulate $10,000. To do so, you plan to make deposits of $1,500 per year - with the first payment being made a yea
Jet001 [13]

Answer:

5.4 years

Explanation:

Future value is the value of the calculated by compounding a specific present value using a specific discount rate

Payment = $1,500

Rate = 9.56%

Future value = $10,000

We will use the following formula to calculate the numbers of years.

Future Value = Payment x [ ( 1  + r)^n - 1 / r ]

$10,000 = $1,500 x [ ( 1 + 9.56%)^n - 1 / 9.56%

$10,000 x 9.56% / 1,500 = ( 1 + 9.56%)^n - 1

0.6373 +1 = 1.0956^n

1.6373 = 1.0956^n

Log 1.6373 = n log 1.0956

n = log 1.0956 / Log 1.6373

n = 5.4 years
