Fifty randomly selected students were asked the number of speeding tickets they have had. The results are as follows:
| Tickets | Frequency |
|---|---|
| 0 | 8 |
| 1 | 15 |
| 2 | 21 |
| 3 | 3 |
| 4 | 2 |
| 5 | 0 |
| 6 | 1 |
Round your answers to two decimal places.
The mean is:
The median is:
The sample standard deviation is:
The first quartile is:
The third quartile is:
What percent of the respondents have had at most 2 speeding tickets?
6% of all respondents have had at least how many speeding tickets?

Based health promotion models, theories, and practice, make two venn diagrams. One should have three circles, one for each of 3 theories/models you have selected and are most interested in. The second one should also have three circles for three different strategies for health education. Compare and contrast the theories/models in the first and compare and contrast the three strategies in the second. You may use a digital tool for this or done them long hand on paper and take a picture to submit.

Which of the following stocks is most likely to be priced highest? Assume that all stocks pay $3 dividend per share per year and are the same in all other aspects.
a)A stock whose annual dividend is expected to grow by 12% for the first two years and then 4% thereafter, with the discount rate of 12%.
b)A stock whose annual dividend is expected to not grow, with the discount rate of 12%.
c)A stock whose annual dividend is expected to grow by 4% per year forever, with the discount rate of 12%.

Describe what Adam Smith meant by the “invisible hand.” Smith first used this metaphor in the context of how capitalists make decisions to invest in the most profitable activities. Why do you think many economists think this metaphor is very useful to explain the mechanism underlying a presumed compatibility between selfish interests and a successful social provisioning in capitalist economies? Do you think the fact that Smith used the words “invisible hand” very sporadically (only three times) in his work deserves some kind of scrutiny?

Although Java has the rule that the left operand of every binary operator is evaluated before the right operand, most languages give the compiler the freedom to choose which operand is evaluated first. When expressions have side effects, the value of the expression can be different depending upon which order is used. Give an example in C++ of an expression whose value depends upon the evaluation order. Show the orders that produce different values and the values they produce. Explain what side effect is the expression contains.

Choosing a Form of Ownership Please respond to the following with a 250-300 word response:
From the e-Activity, describe the most appropriate form of ownership for your new franchise based on your current financial situation. Provide specific examples to support your response. Assume the form of your new business will be a partnership (if you have not already done so). Discuss the types of conflicts that may arise and how you could prevent them from arising in the first place.

A single crystal of a metal that has the FCC crystal structure is oriented such that a tensile stress is applied parallel to the [110] direction. The critical resolved shear stress for this material is 1.75 MPa.
1) Calculate the magnitude of applied stress necessary to cause slip to occur on the (111) plane in the (1-10) direction.
2) Calculate the magnitude of applied stress necessary to cause slip to occur on the (111) plane in the (10-1)direction.
3) Which of these two slip systems is the most favourably oriented (which system will see first plastic deformation)?

Waymo is a division of Alphabet (Google’s parent company) that is developing the technology for driverless
cars. Waymo CEO John Krafcik is under pressure to offer a commercial driverless taxi service in the Phoenix
area as soon as Fall 2018. Analysis at web-site arstechnica.com suggests that Waymo has by far the most
advanced technology available for this type of service.
Is it likely that being first into this market will give them a large advantage? Is Waymo likely to earn
unusually high accounting profit for a long period of time? Discuss using concepts from this class.

Write two algorithms to find both the smallest and largest
numbers in a list of n numbers.
In first algorithm, you simply write one loop to find the minimum
and maximum. So there will be 2(n - 1) comparisons.
In second algorithm, you try to find a method that does at most
1.5n comparisons of array items.
Determine the largest list size (i.e., n) that Algorithm 1 can
process and still compute the answer within 60 seconds. Report how
long it takes Algorithm 2 to compute this answer.
