SUBJECT: Health insurance—Changes

Unlike many companies, Bright Manufacturing has always paid a hundred % of medical car insurance for it’s employees, absorbing the recent 10–20 percent annual cost increases in order to provide this important benefit. This year; Blue Cross gave us some terrible news: the cost increase for our employee’s medical coverage would be a staggering fourty percent per month next year

To mange the increase and continue to offer you and your family highquality medical coverage we have negotiated several changes with Blue Cross; a new cost saving alternative is also being offered by us:

Under the Blue Cross Plus plan, copay amounts for office visits will be ten dollars next year/ $50 for emergency room visits. 80 % of employees’ insurance coverage (including 10 percent of the cost increase) will be paid by Bright next year and 100 % of the prescription drug costs (including a 23 percent cost increase). The remaining twenty percent of medical coverage will be deducted by us monthly from your salary, if you choose to remain on a Blue Cross Plus plan. We realize this is alot, but its still less than many companies charge their employees.

A fully paid alternative health plan, Blue Cross HMO, will now be provided by Bright at no cost to employees. But be warned that there is a deadline. If you want to switch to this new plan you must do so during our open enrollment period, Nov. 20 to December 1, and we will not consider applications for the change after that time so don’t get your forms in late.

There are forms available in the Human Resources office for changing your coverage. They must be returned between November 20 and December 1. If you wish to remain on a Blue Cross Plus policy, you do not need to notify us; payroll deductions for company employees on the plan will occur automatic beginning January first.

If you have questions, please call our new Medical Benefits Information line at ext. 3392. Our Intranet sight will also provide you easy with information about health care coverage online if you click the “Medical Benefits” icon. Since our founding in 1946, we have provided our company employees with the best medical coverage available. We all hate rising costs and although things are looking bleak for the future but we’re doing all we can do to hold on to this helpful benefit for you.

One criticism of employer provided health insurance in the U.S. is that it is tax preferred. Why is this a point of criticism? Who benefits most from this policy? Who doesn’t?

Which of the following is a strong ethical or philosophical issue around the development of artificial intelligence?

Select one:

A. AI rights within society; For example, if an AI killed a human, would the developer be punished or the AI? If the AI, what would that punishment look like? Another example: if AI have emotions based in experience, do they have the right to express those emotions? If an AI is feeling frustrated at the inability to complete a task, do they have the right to express frustration through tears, freaking out, or pouting? Would this change the way they interact with humans?

B. Are AI able/allowed to have sexual experiences, romantic relationships (with other AI or humans), spirituality, and altered states of consciousness?

C. The potential for AI to enslave or eliminate the human species; If AI has the potential to become much more intelligent than humans and it analysis threats to the Earth's existence, it could determine that humanity is the greatest threat and enslave us or eliminate us. How do we prevent that from happening? Or, is it valid for AI to identify us as a threat and seek the upper hand?

D. All of the above

Which of the following statements concerning models of product differentiation, if any, are correct?

You are conducting a study to see if the proportion of voters who prefer Candidate A is significantly more than 47%. With Ha : p > 47% you obtain a test statistic of z = 1.997. Find the p-value accurate to 4 decimal places. p-value =

You are conducting a study to see if the accuracy rate for fingerprint identification is significantly less than 0.62. Thus you are performing a left-tailed test. Your sample data produce the test statistic z = − 2.853. Find the p-value accurate to 4 decimal places. p-value =

The Dean of ASBE School of Business is concerned that grades in the MBA program are distributed appropriately. Too many high grades or too many low grades would pose a problem. We wish to test the claim that the mean GPA of ASBE students is smaller than 3.3 at the .05 significance level. The null and alternative hypothesis would be: H 0 : μ = 3.3 H a : μ ≠ 3.3 H 0 : p = 3.3 4 H a : p < 3.3 4 H 0 : μ = 3.3 H a : μ > 3.3 H 0 : μ = 3.3 H a : μ < 3.3 H 0 : p = 3.3 4 H a : p > 3.3 4 H 0 : p = 3.3 4 H a : p ≠ 3.3 4 Correct The test is: left-tailed right-tailed two-tailed Correct Based on a sample of 50 student grades, the sample mean GPA was 3.29 with a standard deviation of 0.06 The test statistic is: Incorrect (Round to 3 decimals) Based on this we: Reject the null hypothesis Fail to reject the null hypothesis

Do larger universities tend to have more property crime? University crime statistics are affected by a variety of factors. The surrounding community, accessibility given to outside visitors, and many other factors influence crime rate. Let x be a variable that represents student enrollment (in thousands) on a university campus, and let y be a variable that represents the number of burglaries in a year on the university campus. A random sample of n = 8 universities in California gave the following information about enrollments and annual burglary incidents.

(a) Use a calculator to verify that Σx = 151.0, Σx² = 3252.58, Σy = 246, Σy² = 10438 and Σxy = 5430.8.

Compute r. (Round to 3 decimal places.)

(b) Compute the sample correlation coefficient r for each of the following data sets and show that r is the same for both. (Use 3 decimal places.)
