For years, the restaurant Tokos’ Tacos had outdoor service at picnic tables.  During that time, the average tip left by customers was $3.20.  Last year, the restaurant expanded and also had indoor seating.  The shop owner collected a sample of 55 bills from last year. The mean tip amount from this new sample was $3.72 with a standard deviation of $2.84. Using a 10% significance level, perform a hypothesis test to see if the mean tip amount increased after the restaurant expanded. a) On your scrap paper, write the hypotheses using appropriate notation. b) Calculate the test statistic, using the formula.  (Type it in the answer box, but show all work on scrap paper.) c)  Find the p-value using StatKey.  (Type it in the answer box.) d)  Write out the conclusion in the context of the problem.  (Type it in the answer box.)

Use this set-up for Problems 48-52: As of April 5, 2021, the average cost of a wedding in Missouri was determined to be $20,058 (according to valuepenguin.com). Suppose the population standard deviation of wedding costs is $7,500. To determine if the average cost of a wedding in Illinois is more than Missouri, you decide to take a sample of 36 weddings and perform a hypothesis test. Suppose your simple random sample had an average cost of $22,333. You decide to use a significance level of 0.05.What hypotheses would be used to determine if the average cost of a wedding in Illinois is more than the average in Missouri?

Use this set-up for Problems 19-21:You choose to park your car in a metered parking spot where the cost of parking for 1 hour is $1.50. The cost of a parking ticket is $15. Historically, the local police only catch one out of every 12 parking violators in a given hour. You are trying to determine if it’s worth paying the meter or if you’d be better off to not pay the meter and just take your chances of getting a parking ticket.Complete the probability table below, under the assumption that you do NOT pay the parking meter. (In other words, the two rows of the table represent the two outcomes–you park for free or you have to pay a parking ticket) Payment Probability _______ ________ _______ ________  Calculate the expected value of your payment in this situation.

Enroute phaseScenario: The paramedic unit is dispatched to an elementary school nurse’s office for a 7-year-old female who developed difficulty breathing and a rash shortly after eating lunch. The call was received at 1147. Estimated response time is 6 minutes. The paramedic is partnered with an EMT, and a BLS engine crew is also en route. The temperature is 72°F (22°C) and skies are clear. According to the school nurse, the child has a known peanut allergy and her symptoms started within minutes of exposure. The school has an EpiPen available and is awaiting EMS arrival.On scene phaseScenario:The patient (25 kg) is found sitting upright in the school nurse’s office, visibly distressed. She is scratching at her neck and chest, which are covered in raised, red hives. Her lips are swollen, and she is audibly wheezing. The child is anxious and only able to speak in two- to three-word phrases. The nurse confirms that she did not yet administer the EpiPen but did place the child on oxygen via non-rebreather mask. The child’s caregiver has been contacted and is en route to the school.Vital signs: BP 88/52, HR 144, RR 30, SpO₂ 91% on oxygen, Temp 98.4°F (36.9°C).Post scene phaseScenario:The child’s breathing improves within minutes of receiving epinephrine. She is now able to speak in full sentences and is less anxious. Oxygen saturation has increased, and the hives are beginning to fade. IV access is established, and the child remains on 4 L/min oxygen via nasal cannula. The caregiver meets the crew during transport and rides in the front seat of the ambulance. The child remains stable and alert but still complains of a “tight throat.” En route, you prepare for possible recurrence of symptoms. Updated vitals: BP 94/60, HR 126, RR 20, SpO₂ 97%, Temp 98.4°F (36.9°C). What should be included in your documentation and hospital handoff?

Enroute phaseScenario:The paramedic crew is dispatched to a private residence for a 21-year-old female who was found unresponsive in her bedroom by her roommate. The call was received at 1535. The response time is estimated at 7 minutes. The paramedic is partnered with an EMT, and an ALS supervisor is en route. It is a mild spring afternoon, 64°F (18°C), and traffic is light. The roommate reports by phone that the patient has a history of depression and may have ingested “a bunch of pills.” The patient takes amitriptyline and alprazolam, according to the caller. Law enforcement is not yet on scene.Which medication mentioned by the caller is most concerning for life-threatening overdose effects?
