Mr. Vaughn, a 27-year-old man, is hiking in the woods near his home in the American Midwest. He feels a sharp stinging sensation on his left ankle. As he looks down he sees a dark colored snake moving off the trail into the woods. Mr. Vaughn calls the ED at the local hospital. He tells the nurse what has happened. What should the nurse tell Mr. Vaughn? What actions should the nurse take at this time? Mr. Vaughn is brought to the ED via the paramedics along with a park ranger. The park ranger used the patient's description of the snake and determined that it was a pit viper. What is the priority of care for Mr. Vaughn? When the Mr. Vaughn's wounds are reassessed, the nurse notes heavy bleeding from the puncture site. What should the nurse's next actions be? Why?

1, 33% of consumers read the ingredients listed on a product's label. For a sample of 265 consumers, what is the probability that between 80 and 103 of them read the ingredients listed on a product's label?
2.
The hotel room rate in New York City is normally distributed with a mean of $294 per night. Assume that the standard deviation is unknown.
If 23% of the New York City hotel room rates are more than $328 per night, what is the variance? (Remember the label.)
3.
The Economic Policy Institute reports that the average entry-level wage for male college graduates is $22.23 per hour and for female college graduates is $18.97 per hour. The standard deviation for male graduates is $3.94 and for female graduates is $3.02. Assume wages are normally distributed.
If 30 female graduates are chosen, find the probability the sample average entry-level wage is at least $19.85

4. Julie visits the local park 90 times, and sees her favorite pigeon 38 times. Let p be the probability that Julie sees the pigeon on any given visit, and assume that whether Julie sees the pigeon on some visit is independent of whether she sees the pigeon on any other visit.
(a) Construct a 90% two-sided confidence interval for p.
(b) Julie believes that there is a 50% chance that she sees the pigeon when she visits the park. Is your interval in part (a) consistent with that belief? Explain your answer.
(c) Test Julie’s claim from part (b) with a hypothesis test. Use a significance level of α = 0.05. Perform the test by comparing a test statistic to a critical value found in the tables in the back of your textbook.
(d) Perform the test in part (c) using a p-value.

Rental Summary
Calculate the Amount Due.
amtDue = baseCharge + mileCharge
Print the Customer summary as follows:
Rental Summary
Rental Code: The rental code
Rental Period: The number of days the vehicle was rented
Starting Odometer: The vehicle's odometer reading at the start of the rental period
Ending Odometer: The vehicle's odometer reading at the end of the rental period
Miles Driven: The number of miles driven during the rental period
Amount Due: The amount of money billed displayed with a dollar sign and
rounded to two digits. For example, $125.99 or $43.87
Final Check
Remove ALL print code from your script, except for the Rental
Summary.
The following data will be used in this final check:
Rental Code: D Rental Period: 5 Starting Odometer: 1234 Ending Odometer: 2222
Your final output should look like this:
Rental Code: D
Rental Period: 5
Starting Odometer: 1234
Ending Odometer: 2222
Miles Driven: 988
Amount Due: $324.40

onsider the following questions: How much does milk cost on the East Coast of the United States? How many minutes does it take to drive 30 miles at an average speed of 55 miles per hour? What is the age difference between you and your siblings? How many hours of sleep do teenagers get during the school year compared to summer vacation? Define each question as being or not being a statistical question and explain why.

Use graphs to illustrate the difference between a fuel tax and CAFE standard on the marginal cost (to the consumer) per mile driven.
Use what you know about elasticity to discuss why a fuel tax would need to be very high in order to bring about a substantial reduction in miles driven.
Use what you know about supply and demand to discuss why fuel efficiency standards might actually result in more miles driven.
