A random sample of 310 found that 57% of the readers owned a personal computer. Is there sufficient evidence at the 0.01 level to support the executive's claim?

-State the null and alternative hypotheses.

-Find the value of the test statistic. Round your answer to two decimal places.

-Specify if the test is one-tailed or two-tailed.

-Determine the decision rule for rejecting the null hypothesis, H0.

-Make the decision to reject or fail to reject the null hypothesis.

Chuck Stout is the RM for the Holiday Inn Express. His 220-room property normally sells 85 percent of its rooms on Tuesday nights at an ADR of $141.50. All variable costs related to selling his rooms are $55.00 per room. The DOSM at his Holiday Inn Express is proposing to place a bid to sell 125 rooms for a Tuesday night next month at a rate of $109.00 per room. Chuck believes that if the hotel wins this group rooms bid, the transient room sales for that day will ensure a sell-out at the rate of $141.50.

What would be the total amount of after-variable costs rooms’ revenue the hotel will achieve if it wins the group rooms contract?

What would be the after-variable room’s income if the hotel does not win the contract?

Question 6

John Fogarty was staying at the Homelike Hotel and took a bath in the tub provided with his room. When he was ready to get out of the tub, he pulled on a device in the wall of the tub called a “Soap & Grab,” which was designed to be used for the purpose of helping people pull themselves out of the tub. Instead of performing that function, however, the “Soap & Grab” pulled out of the wall and hit John in the face, breaking his nose and giving him severe cuts. John would like to sue the Homelike Hotel for negligence but has no direct evidence of what they did or did not do concerning the “Soap & Grab.” Identify the legal doctrine under which John might establish a duty against the hotel in a negligence lawsuit and explain whether John’s situation meets the requirements of that legal doctrine.

You are given the sample mean and the population standard deviation. Use this information to construct the​ 90% and​ 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. If​ convenient, use technology to construct the confidence intervals. A random sample of 45 home theater systems has a mean price of ​$120.00. Assume the population standard deviation is ​$17.50.

this case study and question on it

Misr General Hospital has determined that its medication management
system is "broken". Costs are growing rapidly, doctors are complaining
that needed medicines are not available, while the pharmacy points
fingers at the internists saying that they use so many high price antibiotics
that they don't have the budget to buy other medications that are also
needed.
The recently instituted measurement of medication errors disclosed a
large number of them, a significant percentage of which has to do with
administration at the wrong time. Possibly related to the issue of
medication errors is the fact that post-hysterectomy infections have
increased greatly; the nurses in the operating suite claiming that patients
are not receiving their antibiotic prophylaxis properly. The quality
steering committee developed the following set of measure to determine
the extent of the problems and to help analyze their causes:
Internal Medicine:
Measure: The use of third generation cephalosporin as first line treatment
for the diagnosis of pneumonia.
Numerator: The number of patients over the age of eighteen who were
diagnosed on admission with pneumonia and received one of the
designated drugs within 24 hours of admission.
Denominator: All patients over the age of eighteen with the admission
diagnosis of pneumonia.
Frequency of measure: Monthly.

^{Obstetrics and Gynecology:}
Measure: Proper application of prophylactic antibiotics for abdominal
hysterectomy.
Numerator: All adult patients who received the first dose of antibiotics
within one hour of the start of the operative procedure of abdominal
hysterectomy.
Denominator: All adult patients who underwent the operation of
abdominal hysterectomy.
Frequency of measure: Every 3 months.

_{Nursing Service:}
Measure: Mis-timed administration of medications to patients.
Numerator: Medications administered within 30 minutes (plus or minus)
of the time ordered, or if the order is imprecise, such as 3 times a day,
within the time set by nursing policy.
Denominator: All medications ordered.
Frequency of measure: Sampling one day each week for each nursing
unit.

Pharmacy:
Measure: Frequency of medications ordered by physician not being
available for dispensing.
Numerator: Each instance of a medication ordered by a physician not
being in stock.
Denominator: None-measure is simple number.
Frequency: Monthly.

For each four measures, answer the following questions:
1. Do the numerator and denominator actually measure what is being
intended?
2. If not, why not?
3. Is the frequency of measurement appropriate?
4. If not appropriate, what is the proper frequency?
Do you have any other comment to make about any of the four measures?

QUESTIONS ABOUT MEDICATION ERRORS

A. If the prescription is wrongly written but the right dose is
administered at the right time, is it a medication error? If not, is it a
near miss?
B. If the order is wrongly transcribed, but the right dose is
administered at the right time, is it a medication error? If not, is it a
near miss?
C. If the order neglects to note that the patient is reported to be
allergic, is it a medication error? If not, is it a near miss?
D. If the order does not take drug-drug interactions into account, is it a
medication error? If not, is it a near miss?
E. If the prescription is correct, but the medication is administered to
the wrong patient, who does not suffer any ill effect, is it a
medication error? If not, is it a near miss?
F. If the patient's renal function necessitates a lower dose of
medication and this is not recognized, is it a medication error? If
not, is it a near miss?
G. If the usual adult dose is administered to an 85-year old patient
who suffers a well described dose-related adverse reaction, is it a
medication error? If not, is it a near miss?
H. A patient unexpectedly suffers a convulsion. He has received the
recommended dose of a drug that is contraindicated in the presence
of a seizure disorder, which he wasn't known to have. Was the
patient the victim of a medication error? If not, is it a near miss?
I. A diabetic patient has a renal arteriogram. Four days later, it is
noticed that her serum creatinine had increased three fold. She
received no medications known to cause kidney failure. Is it a
medication error? If not, is it a near miss?
J. A patient treated for pneumonia is found dead. He was last checked
three hours ago. The antibiotic he should have received two hours
ago was not given. Did he die as a result of a medication error?
K. If the answer to J is "no", was there a medication error? If not, is it
