The cost of weddings in the United States has skyrocketed in recent years. As a result, many couples are opting to have their weddings in the Caribbean. A Caribbean vacation resort recently advertised in Bride Magazine that the cost of a Caribbean wedding was less than $10,000. Listed below is a total cost in $000 for a sample of 8 Caribbean weddings. At the 0.025 significance level is it reasonable to conclude the mean wedding cost is less than $10,000 as advertised? 12.4 8.5 10.1 12.6 10.5 9.1 9.8 11.2

a. State the null hypothesis and the alternate hypothesis. Use a .025 level of significance. (Enter your answers in thousands of dollars.) H0: μ ≥ H1: μ <

b. State the decision rule for 0.025 significance level. (Negative amount should be indicated by a minus sign. Round your answer to 3 decimal places.) Reject H0 if t <

c. Compute the value of the test statistic. (Negative amount should be indicated by a minus sign. Round your answer to 3 decimal places.) Value of the test statistic

HI please answer all parts of my question. Thank you so much! I will rate you!

Why do we call cardiac muscle to be a syncytium of many individual muscle cells? What is the name of membranes that connect longitudinally adjacent muscle cells?

As you know the mechanism of organophosphates involves irreversible inhibitors of AChE. Organophosphates have been used in several murders (VX used to kill the half-brother of North Korean dictator Kim Jong Un; Sarin gas used to kill 12 people on the Tokyo subway by the Japanese cult Aum Shinrikyo in 1995).The death of a victim is associated with difficulty of breathing and irregular heart rate. Please discuss the physiological mechanisms of organophosphates action on the lungs and on the heart.

An overweight 75 year old male with a history of coronary artery disease and shortness of breath on exertion celebrates his granddaughter’s wedding. He goes for several fast dances with the bride, after which he collapses on the floor, turns blue, and dies within minutes. What is the reason for his death?

Select one:

a. The break-even price for taking a long position in this call option is $100.

b. Buying the call option will give the investor some advantages over buying the underlying stock

c. The maximum profit for taking a long position in this call option is unlimited while the maximum loss for taking a long position in this call option is $5.

d. The investors should buy the call option if he expects the price of the underlying stock in the next two months will be more than $100.

The market supply is given by P = 20 + Q. The market demand for good X is given by P = 100 - 2Q - P_Z. P_Z is the price of a related good Z.

Find the market equilibrium for good X when P_Z equals 38; denote the equilibrium as P1 and Q1. Find the market equilibrium for good X when P_Z equals 44; denote the equilibrium as P2 and Q2.

1. Using the midpoint method, the price elasticity of supply for good X when its price changes from P1 to P2 is ________.

2. On the first-half of a letter-sized paper, illustrate the effect of the change in P_Z on the market for good X, using a completely-labelled supply and demand graph, with P1, P2, Q1 and Q2 and their values clearly indicated.

3. On the second-half of the paper, provide an example of goods X and Z, explain why a change in P_Z affects the market for X, and outline the equilibrium process in the market for good X due to the change in P_Z.

Client Profile

Betty, a 50-year-old woman, came to this country with her parents when she was 7 years old. The family members worked as migrant farmworkers until they
had enough money to open a restaurant. Betty married young. She and her husband worked in the family restaurant and eventually bought it from the parents.
They raised seven children, all grown and living on their own. Betty and her husband live in a mobile home close to the restaurant. She does not work in the family
restaurant anymore because she worries excessively about doing a poor job. Betty no longer goes out if she can help it. She stays at home worrying about how she
looks, what people think or say, the weather or road conditions, and many other things. Betty is not sleeping at night and keeps her husband awake when she roams
the house. She keeps her clothing and belongings in perfect order while claiming she is doing a poor job of it. She does not prepare large family dinners anymore,
though she still cooks the daily meals; one daughter has taken over the family dinners. This daughter has become concerned about Betty being isolated at home and
worrying excessively and calls the community mental health center for an appointment for Betty.

Case Study

Betty presents at the community mental health center accompanied by her husband, her children and their spouses, several grandchildren, and a few cousins.
When Betty's name is called and she is told that the nurse is ready to see her, she frowns and says: "What will I say? I don't know what to say. I think my slip is showing. My hem isn 't straight." Betty says she wants her whole family to go in to see the nurse with her. The nurse notices that Betty is extremely well-groomed and dressed in spite of concerns she has been voicing about her appearance. Before the psychiatric nurse interviews Betty alone, she hears from the daughter that Betty "worries all the time" and although she has always been known to be a worrier, the worrying has become worse over the past six or eight months. The husband shares that his wife is keeping him awake at night with her inability to get to sleep or stay asleep. The nurse interviews Betty alone. The nurse notices that Betty casts her eyes downward, speaks in a soft voice, does not smile, and seems restless as she taps her foot on the floor, drums her fingers on the table, and seems on the verge of getting out of her chair. Themes in tl1e interview include: being tired, getting tired easily, not being able to concentrate, not getting work done, trouble sleeping, worrying about whether her husband loves her anymore and whether she and her husband have enough money, and not having the energy to attend to the housework or her clothing. The nurse has the impression that Betty's anxiety floats from one worry to another. There is no convincing Betty that she looks all right. Any attempt to convince her that she need not worry about something, in particular, leads to a different worry before coming back to tl1e earlier worry. The community mental health psychiatrist examines Betty and, after a thorough physical examination and lab studies, finds nothing to explain her fatigue and difficulty sleeping other than anxiety. Betty produces her medicine bottles and says she is currently taking only vitamins, hormone replacement, and calcium. The psychiatrist asks the nurse to contact Betty's family health care provider to get information on any medical or psychiatric conditions he is treating her for; the report comes back that she has no medical diagnoses and the family health care provider thinks she suffers from anxiety. The psychiatrist prescribes buspirone (BuSpar) for Betty. Two weeks later, during a home visit to Belly, the nurse learns, with some probing, that Betty is upset with her husband for loaning all their savings to the daughter and her husband to build a new home, while they continue to live in an older mobile home. At the end of the n nurse's home visit, Betty's daughter arrives and tells the nurse that she wonders iI Betty is making any progress. Betty also worries she is not getting better and asks the nurse about taking some herbal medicines containing Kava and Passaflora that her sister got from a curandara (folk healer); her sister wants to take her to see the curandara and have her do a ritual to cure the evil eye
that was placed on Betty and made her sick.

Can You help me write an SBAR for this case study Thank You

Use a 2 step binomial tree to value a new exotic derivative. Draw the tree and label the stock prices and derivative values at each node. The option expires in 6 months. The interest rate is 10% annually continuously compounded. The Strike Price (K) is 100. The spot price is at 100. U= 1.2 and D= 0.8 for each quarterly period. The payoff of this derivative is (ST/K). By this I mean that the payoff is the price of the underlying stock divided by the Strike Price.
