1) You have extracted your targeted plasmid from Milariuza. equilirus in your home. Because you do not have an expensive nanodrop machine, you decided to run a gel to determine the concentration of your sample. However, you also don’t have Tris-acetate, thus can’t make any TAE buffer. Being a smart student, you realize you can simply make 1X TBE buffer instead of 1X TAE buffer for your experiment. You will need 800ml TBE buffer for both making the gel and use it as a running buffer. You do not have any access to pipettes because you left them at school, and you only have large graduate cylinders. This means that any measurement below 10ml is inaccurate. The balance you have can only measure accurately above 100mg. Please show all works.

500mM Tris-Borate                                50M Tris-Borate

10mM EDTA                                        EDTA (MW ? 300)

Zoe is testing to see if UCI students are more stressed out than the normal
person is. The mean stress level of the average person is 50 with a known
standard deviation of 10. Amy is going a two-tailed test with α = .10. The null
hypothesis is μ = 50. What precisely is μ the mean of?

The average UCI student commutes 6.3 miles to school, with a known standard
deviation of five miles. Amy believes that social science majors are different from
the average UCI student. She gets a sample of six social science majors and
asks them how far they commute. They answer 4, 13, 11, 7, 15, 10. Do a z-test
to see if Amy’s belief is true. Please calculate the z-statistic for this data.

Now, for the above question, state the critical value, and come to a conclusion
about Amy’s belief. Let α = .01. Make it a two-tailed test.

What is the p-value for the experiment in questions 13 and 14? Answer to
four digits past the decimal point, such as .3264.

2. Speeds of the fastest cars at a race location are normally distributed with a mean of 64.8 mph, and standard deviation 8.9 mph. Find the speed that separates the slowest 6% of vehicles from the rest. Round your answer to two decimal places.

3. Refrigerators of a certain type have lifetimes that are normally distributed with mean 675 hours and standard deviation 44.5 hours. Find the lifetime (in hours) that would separate the longest 1.5% from the rest. Round your answer to one decimal place.

4. The board of education that administers the CPA examination in a certain state found that the mean score on the test was 595 and the standard deviation was 72. If the board wants to set the passing score so that only the best 12% of all applicants pass, what is the passing score? Assume that the scores are normally distributed. Round your answer to one decimal place.

5. Scorecard of children’s in elementary school are normally distributed with a mean of 100 and a standard deviation of 15. Find the IQ score separating the top 12.5% from the others. Round your answer to two decimal places.

Prepare a schedule showing the amortization of a $12,000 loan to be repaid in 10 end-of-year installments that include interest at a rate of 6%. Jared and Courtney Jill own a parcel of fertile farm land which a local farmer has offered to rent for a period of 10 years. He is willing to make a payment of $20,000 today or pay an ordinary annuity of $3,400 at the end of each of the next 10 years. Which payment method should Jared and Courtney accept if the appropriate rate of return is 9%? A group of five faculty members at a Midwest University have recently purchased several acres near the school. They plan to gravel it and rent the parking spaces to commuting students. The cost of the project is $100,000. They paid $25,000 cash and are financing the balance with a note at 7.0% annual interest to be paid off in five equal annual payments with the first payment to be made at the end of the first year. The rental receipts are to be placed in an account for future improvements and cannot be used to repay the loan. If the annual payments are shared equally, how much would each member need to contribute annually to pay off the loan?

Describe the ideal future higher education would work best for you, will the high-ed still need? Describe the ideal of future K-12 education for the next generations, will the K-12 education still necessary? A kid named John Smith, who will be born in 2040. Describe what his education/learning experience will be. Is he still going to physical school? How many years of learning he needed before he put himself in the workplace. Who plays important roles in his education? Will technology impact a more social divide society? What are the factors that can potentially cause the divide and what the people in this generation can make the difference to ensure the next generation obtain the best learning experience? How do we get our kids ready for the future? Explore the following learning resources before answer the questions above. Ask yourself, what you really like and interested to learn?

The GSS 2014 respondents in the U.S. were asked, "How important do you think that being a Christian is for being truly American?" Responses were measured on a 4-point scale: 1=very important, 2=fairly important, 3=not very important, 4=not important at all. We will treat this variable as interval/ratio. Those with a high school degree had an average score of 2.35 (s = 1.21, n = 189). Those with a bachelor’s degree had an average score of 3.05 (s = 1.05, n = 61).

a)State the research and null hypothesis for a one-tailed significance test of means.

b) Calculate the t statistic

d) If you had conducted a two-tailed test with alpha=.05, would your decision have been different?

A. In a two-tailed test, we would fail to reject the null hypothesis of no difference.

OR

B. In a two-tailed test, we would reject the null hypothesis of no difference.

Activity 3: Which procedure?
For each question, determine which inference procedure is appropriate (perform hypothesis test or construct a confidence interval), and identify the parameter of interest (p, p1 – p2, µ, µ1 – µ2, µd).

The Survey of Study Habits and Attitudes (SSHA) is a psychological test that measures the motivation, attitude toward school, and study habits of students. Scores range from 0 to 200. A selective private college gives the SSHA to an SRS of both male and female first-year students. The data for the women are as follows: 154 109 137 115 152 140 154 178 101 103 126 126 137 165 165 129 200 148 Here are the scores of the men: 108 140 114 91 180 115 126 92 169 146 109 132 75 88 113 151 70 115 187 104 Most studies have found that the mean SSHA score for men is lower than the mean score in a comparable group of women. Is this true for first-year students at this college? Use a 1% significance level

Economists believe people should get paid according to the value of the output they produce. This is fairly easy to determine when you produce something physical, such as cupcakes. However, it becomes very difficult to measure if you are providing a service (perhaps teaching, or you're a doctor treating a medical condition). Regardless of how you measure the value of the output, the more productive you are the more valuable you are in the market to potential employers. This is the reason many economists are against the minimum wage and are for programs that contribute to improving an employee's productivity (such as education and training). There is surprising agreement with just how important education is in minimizing income inequality among economists.

Given this information, what would you recommend to policy makers? What do you think about various school districts having vastly different access to resources around the state, or even the country? Recall, spending more money on education does have an opportunity cost - be sure to include that in your answer. Note, this is NOT a couple sentence discussion. I'm expecting you to clearly demonstrate deep reflective thought.
