The table below gives the number of hours spent unsupervised each day as well as the overall grade averages for seven randomly selected middle school students. Using this data, consider the equation of the regression line, yˆ=b0+b1x, for predicting the overall grade average for a middle school student based on the number of hours spent unsupervised each day. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would not be appropriate to use the regression line to make a prediction if the correlation coefficient is not statistically significant.

Step 3 of 6 :  

Find the estimated value of y when x=5. Round your answer to three decimal places.

1. Researchers evaluated whether the teen pregnancy rate at a local high school with abstinence-only sex education differed from the average teen pregnancy rate statewide. At the time of the study, the statewide rate (regardless of type of sex-education received) was 12%. A random sample of 200 female students was selected from the local school: thirty-seven of the students were either currently pregnant or had been pregnant previously, whereas 163 students were not/had never been pregnant.

2. White (2001) was interested in the effect of two different types of exercise programs for improving time to run a marathon. He was one of the first researchers to evaluate how each type of exercise program affected the running times for participants of both normal and obese body types.

The nurse in the ED has been notified that a school bus carrying a high school football team has been involved in a head-on collision with a semi-tractor trailer truck. There are multiple injuries and a possible death. A small community hospital was notified of the accident and told to expect 35 victims.

1. Should the small local emergency department initiate their disaster plan? Why or why not?

There are multiple players with moderate to severe injuries. Three ambulances are at the scene.

2. Discuss what factors should be discussed in the decision to send the injured to the local community hospital versus other emergency departments in the area.

The driver of the tractor trailer truck was pronounced dead at the scene. Several of the football team members saw the driver dismembered as the truck hit the bus, and were unable to move from the scene until someone pulled them away.

3. What actions should be taken by members of the interprofessional health care team to help these victims and other people involved with the accident to cope?

Scenario # 2 Your facility is a large children’s hospital in north Texas. Until recently your facility was part of a larger health care facility run by the state. The facility is now corporately owned and operated. During this reorganization period a major fire occurred at a local elementary school. Over 100 injured children were sent to your facility for care. You encountered many problems: care was delayed and inappropriate for many children because of the nature of their injuries due to lack of parental consent for treatment and smoke inhalation and burns. Your task is to develop a disaster plan specifically to address the deficiencies and to reshape your public image following the fire at the elementary school.

A. Researchers examined the relationship between cola consumption and bone loss after fifty. One thousand women were randomly sampled, everyone's cola consumption was recorded over a two month period of time, and bone density measures were also recorded. Researchers found that the more cola consumed, the lower the level of bone density. They concluded that cola consumption leads to loss of bone density.

Evaluation the internal validity.

B. Researchers examined differences in attitudes towards drinking between high school freshman and high school seniors. 400 students completed questionnaires that included information about drinking attitudes. The researchers found that older students maintained more liberal attitudes towards drinking than younger students. The researchers concluded that attitudes towards drinking and alcohol become more liberal with age.

Short Essay Question:

President Ronald Reagan is remembered as a president that won the hearts of many white suburbanites because he opposed school desegregation. He claimed that school desegregation “takes innocent children out of the neighborhood schools and makes them pawns in a social experiment that nobody wants.” Reagan, however, also shocked many white suburbanites when he fired 11,500 air traffic controllers, after they refused to go back to work during their 1981 strike. Reagan’s unprecedented dismissal of skilled workers encouraged other private employers to do the same, undermining the rights of all American workers.

How have the experiences of white and black Americans been similar under specific public policies and political ideologies? How have they been different? Make your argument by using class readings and lectures, with reference to at least two of the following:

In a school district, all sixth grade students take the same standardized test. The superintendant of the school district takes a random sample of 26 scores from all of the students who took the test. She sees that the mean score is 101 with a standard deviation of 10.1793. The superintendant wants to know if the standard deviation has changed this year. Previously, the population standard deviation was 21. Is there evidence that the standard deviation of test scores has decreased at the α=0.01 level? Assume the population is normally distributed. Step 1 of 5: State the null and alternative hypotheses. Round to four decimal places when necessary.

Step 2 of 5:

Determine the critical value(s) of the test statistic. If the test is two-tailed, separate the values with a comma. Round your answer to three decimal places.

Step 3 of 5:

Determine the value of the test statistic. Round your answer to three decimal places.

Step 4 of 5:

Make the decision.

Step 5 of 5:

What is the conclusion?

A school district establishes a vehicle repair shop that provides service to other departments, all of which are accounted for in its general fund. During its first year of operations the shop engages in the fol-lowing transactions:

• It purchases equipment at a cost of $24 million and issues long-term notes for the purchase price. The useful life of the equipment is eight years, with no residual value.

• It purchases supplies at a cost of $4 million. Of these it uses $3 million. In its governmental funds, the district accounts for supplies on a purchases basis.

• It incurs $13 million in other operating costs.

• It bills other departments for $19 million.

For purposes of external reporting, school district officials are considering two options:

• Account for the vehicle repair shop in an internal service fund

• Account for the vehicle repair shop in the general fund

Please prepare the journal entries under the two assumptions. First assume the transactions are recorded in an internal service fund; and then assume the transactions are reported in the general fund.

This policy ensures that all students in grades one to nine are physically active for at least thirty minutes each day through activities organized by the school (Alberta, 2020). Being active is being healthy. As was mentioned in the Dr. Christine Kennedy’s article schools have the potential to help children develop lifelong, healthy eating patterns and encourage physical activity; research supports school-based interventions to increase physical activity and decrease obesity (Kennedy, 2010).

Giving the kids an opportunity to have an active form of break, allows them to get the proper physical attention to the young body. This increase the overall mental and physical health. Kids between ages of 6 to 14 are in the most important period of they life, when the body and bones are forming. Therefore, this initiative that came to Alberta schools in 2005 was widely accepted and implemented by all the schools across the province.

come up with a discussion question. Something that a rival or someone who is against this policy would say.
