In each problem show all steps of the hypothesis test or confidence interval. If some of the assumptions are not met, note that the results of the test or interval may not be correct and then continue the process of the hypothesis test or confidence interaval.

Are there more children diagnosed with Autism Spectrum Disorder (ASD) in states that have larger urban areas over states that are mostly rural? In the state of Pennsylvania, a fairly urban state, there are 245 eight year olds diagnosed with ASDout of 18,440 eight year olds evaluated. In the state of Utah, a fairly rural state, there are 45 eight year olds diagnosed with ASDout of 2,123 eight year olds evaluated ("Autism and developmental," 2008). Is there enough evidence to show that the proportion of children diagnosed with ASDin Pennsylvania is more than the proportion in Utah? Test at the 1% level

The risk management department reviews the nurse chart and dinds that vital signs were taken q8 hours. The unit policy on epidural morphine states that vital signs are assessed q 4 hours x 24 hours and respiratory rate is assessed q 2 hours. The policy also states that an IV must be in place for 24 hours.

1- Which of the standards of professional performance that delinates roles and behaviors for the professional nurse apply to this situation?

2- Did the nurse fulfill her legal responsiblities as a nurse?

A code blue is called, but Mary does not regain consciousness. She is intubated and transferred to the Intensive care unit and placed on a ventilator.

3-  In a court of law, could the nurse's care be considered negligent?

4- If she is found negligent what will happen to the Nurse?

This essential skill asks you to compare and contrast energy conversions in mitochondria with those in chloroplasts. To highlight the similarities and differences in these processes, enter answers to this questions series in the answer field.

1) Both processes involve a hydrogen ion electrochemical gradient. State the location (specific membrane location) and the direction of this electrochemical gradient in mitochondria and in chloroplasts.

2) Both processes involve electrons at a high energy state early in the processes. In the two separate processes, where does the energy carried in these electron states come from?

3) Once some of the energy is extracted from the high-energy electron states, the electrons have to be deposited on some acceptor molecule. Identify this acceptor molecule in both processes (oxidative phosphorylation vs photosynthesis).

(Each of these questions can be answered with a sentence or two.)

Arizona (AZ) immigration restrictions in the short run and long run. Suppose native-born workers and immigrants are equally productive and work in perfectly competitive labor markets, with perfect information and free mobility of labor between US states. AZ voters decide to ban employment of immigrant workers. As a result, immigrants immediately leave AZ and find jobs in other US states. a. Use a supply and demand diagram to show the short run impact of the exit of immigrant workers from the AZ labor market (assume there is one labor market for all of AZ). b. According to your diagram, what happens to the wage rate and overall employment level in AZ in the short run? Explain in one or two sentences. c. What will happen to employment and wages in the AZ labor market in the long run? Explain.

A 16-year-old Asian male presents at the doctor’s office complaining of “sores” on his arms and face.

He states, “everyone thinks I have something contagious and I get depressed about it”. He has recently returned to school and states that he uses hand sanitizer frequently.  This seems to make the sores worse.  He takes no medication for the sores.

Assessment:  VS stable, no signs of fever.  Skin of arms and face are inflamed with vesicles and papules that are weeping and oozing. The patient has eczema.

Let L1 be the language of the binary representations of all positive integers divisible by 4. Let L2 be the language of the binary representations of all positive integers not divisible by 4. None of the elements of these languages have leading zeroes.

a) Write a regular expression denoting L1.

b) Write a regular expression denoting L2.

c) a) Draw a state diagram (= deterministic finite state automaton) with as few states as possible which recognizes L1. This state diagram should be complete: it should handle all strings of 0’s and 1’s.

d) Draw a state diagram (= deterministic finite state automaton) with as few states as possible which recognizes L2. This state diagram should be complete: it should handle all strings of 0’s and 1’s.

What would be the state diagram of the following:

The traffic light cycle will have 5 states:

State 1: Transition into Major (NS) traffic, All lights red

State 2: Left turn signals Major are on

State 3: Major roadway straight green lights on

State 4: Transition into Country (EW) traffic, All lights red

State 5: Country roadway straight green lights on

* In-state only light are listed are not red others are red.

*Major straight-lane is green for 10 sec.

* The transition states (1 and 5) shall be activated for 0.67 sec for the next traffic.

*The country street is green for 6 sec.

*The major road left signals will on by switches which determine if a car is present either the major left-turn lane.

6. Seat Belts A simple random sample of front-seat occupants involved in car crashes is obtained. Among 2823 occupants not wearing seat belts, 31 were killed. Among 7765 occupants wearing seat belts, 16 were killed. The claim is that the fatality rate is higher for those not wearing seat belts. Are Seat Belts Effective? Use alpha=0.01 Hint: We are testing for difference between two proportions. Let P1 indicate the proportion of occupants not wearing seat belts, P2 indicate the proportion of occupants wearing seat belts. Here, we would like to see if seat belt is effective. Therefore, the null hypothesis states H0: P1=P2, where the alternative hypothesis states H1: P1>P2, indicating a right tailed test.

Question 20 (1 point)

The ________ circuit overcomes the problem of false switching caused by noise on the input(s).

A) Schmitt trigger

B) input noise eliminator

C) differentiator

D) input buffer

Confused on this one, mainly the wording. Books states a Schimtt trigger is built in a comparator for hysteresis which helps with noise, but a schimitt triiger is not a "circuit" from what I gather in the text. Out of all the options there, the only one the book refers to as a "circuit" is a differentiator. But it states that is noisy which the question reads from what I gather stops/overcomes the noise.

The other two options are not noted anywhere in the chapter.

My reference material is from Electronic Devices by Floyd 10th Ed Chapter 13. Any help will be appreciated. Thank you.

26. A sample of 1100 computer chips revealed that 62% of the chips fail in the first 1000 hours of their use. The company's promotional literature states that 60% of the chips fail in the first 1000 hours of their use. The quality control manager wants to test the claim that the actual percentage that fail is different from the stated percentage. State the null and alternative hypotheses.
