in 2010, the Maricopa Community College District's enrollment
data showed the following breakdown of students by ethnicity: 54.9%
White; 21.1% Hispanic; 7.9% Black; 4.5% Asian/Pacific Islander;
2.9% Native American; 8.8% Other. Information was collected from a
random sample 0f 300 students in 2017 to determine whether or not
the data has changed significantly. The sample data is given in the
table below. At the α=0.05 level of significance, test
the claim that the ethnic breakdown of students at MCCCD has not
changed significantly since 2010.
Which would be correct hypotheses for this test?
Ethnicity of students in sample:
| Ethnicity | Count |
|---|---|
| White | 137 |
| Hispanic | 71 |
| Black | 27 |
| Asian/Pacific Islander | 12 |
| Native American | 14 |
| Other | 39 |

Several issues have arisen on the Recreation and Wellness Intranet Project. The person from the HR department who was supporting the project left the company, and now the team needs more support from that group. A member of the user group that supports the project is extremely vocal and hard to work with, and other users can hardly get a word in at meetings. You are getting weekly status reports from all of the team members, but many of them do not address obvious challenges that people are facing. The team is having difficulty deciding how to communicate various project reports and documents and where to store all of the information being generated. Recall that the team members include you, a programmer/analyst and aspiring project manager; Patrick, a network specialist; Nancy, a business analyst; and Bonnie, another programmer/analyst.
Tasks
1. Summarize three different communications media that could be
used for getting more support from the HR department and which you
think would be most effective.
2. Prepare a sample of a good weekly progress report that could be
used for this project. Include a list of tips to help team members
provide information on these reports.

Calculate the pH of each of the solutions and the change in pH to 0.01 pH units caused by adding 10.0 mL of 2.67-M HCl to 540. mL of each of the following solutions. Change is defined as final minus initial, so if the pH drops upon mixing the change is negative. a) water pH before mixing = Correct: Your answer is correct. pH after mixing= pH change = b) 0.153 M C2H3O21- pH before mixing = pH after mixing= pH change = c) 0.153 M HC2H3O2 pH before mixing = pH after mixing= pH change = d) a buffer solution that is 0.153 M in each C2H3O21- and HC2H3O2 pH before mixing = pH after mixing= pH change =

A doctor wanted to know if watching a short, 15-minute, anti-smoking video would change people’s attitudes about smoking. Participants were given a survey to determine their attitude toward smoking before and after watching the anti-smoking video. The doctor hypothesized that the participants would have a lower score (have a more negative attitude) after watching the video than before. Answer the questions based on the information given below the questions. Use alpha = .01.
Mean : Before watching = 5.548 After watching = 2.912
Variance : Before watching = 1.212546184 After Watching = 2.193028112
Observations : Before Watching = 250 After Watching = 250
df : 249
t stat : before watching = 21.68455
a. What type of test is this? Be specific.
b. Write the null hypothesis.
c. Write the alternative hypothesis.

On December 31, 2019, Novak Inc. has taxable temporary differences of $2.21 million and a deferred tax liability of $618,800. These temporary differences are due to Novak having claimed CCA in excess of book depreciation in prior years. Novak’s year end is December 31. At the end of December 2020, Novak’s substantively enacted tax rate for 2020 and future years was changed to 30%. For the year ended December 31, 2020, Novak’s accounting loss before tax was $494,500. The following data are also available. 1. Pension expense was $87,600 while pension plan contributions were $111,000 for the year. (Only actual pension contributions are deductible for tax.) 2. Business meals and entertainment were $38,000. (They are one-half deductible for tax purposes.) 3. For the three years ended December 31, 2019, Novak had cumulative, total taxable income of $123,300 and total income current tax expense/income tax payable of $34,524. 4. During 2020, the company booked estimated warranty costs of $31,300 and these costs are not likely to be incurred until 2024. 5. In 2020, the company incurred $150,000 of development costs (only 50% of which are deductible for tax purposes). 6. Company management has determined that it is probable that only one half of any loss carryforward at the end of 2020 will be realized. 7. In 2020, the amount claimed for depreciation was equal to the amount claimed for CCA.
