Regarding the fracture mechanism of metals, polymers and ceramics
(a) Explain why FCC metals show a ductile fracture even at low temperatures while BCC metals do not.
(b) What is crazing? What can you say about the Poisson’s ratio of the crazed material?
(c) Generally, in ceramics, intergranular fracture is preferred to cleavage fracture; however, in metals, transgranular fracture is the preferred mechanism for brittle failure. Why? Use a physical reason supported with an equation in your answer.

Think about and identify several internal and several external environmental factors that affect marketers’ choices across the 4Ps+1 (think about that first section of the marketing plan). Discuss how specific internal and/or external factors can influence what products or services companies sell to customers, and discuss how specific internal and/or external factors can influence effective strategies using the other marketing mix elements.

1) A random sample of 20 male German Shepherds found that their average weight was 112 pounds with a standard deviation of 28 pounds. A random sample of 14 male Dobermans found that their average weight is 107 pounds with a standard deviation of 24 pounds. Assume that weights are normally distributed. Use the Statcato printout below and a 5% significance level to test the claim that the population mean average weight of male German Shepherds (population 1) is more than the population mean average weight of male Doberman Pinchers (population 2). What does this data indicate about the relationship between the weight and the type of dog? Please explain why or why not the categorical variable is related to the quantitive variable?
c) Check all of the assumptions for a two-population mean T-test. Explain your answers. Does the problem meets all the assumptions?
d) Write a sentence to explain the T-test statistic.
e) Use the test statistics and the critical value to determine if the sample data significantly disagrees with the null hypothesis. Explain your answer.
g) Use the P-value and significance level to determine if the sample data could have occurred
by random chance (sampling variability) or is it unlikely to random chance? Explain your answer.

Develop a marketing plan for an existing or a fictitious company that plans to launch kefir chocolate.
This marketing plan should include these parts specifically; product, target market, price, place, promotion and SWOT Analysis of the product.
The parts in the below should be explained deeply.
Product: What is your product? Why do you think this idea would work in Turkey? Provide a 1-sentence mission statement as the producer/marketer of this offering. What is your competitive advantage with 1 sentence?
Target Market: Who is your target market, give a detailed account of your target market; who are they? What bases of segmentation are you using and why? State at least 2 different segmentation criteria that you prefer to use. Refer to the segmentation strategies
Price: What is your pricing strategy? Why are you using this pricing strategy?
Place: Where will you sell your product and why? Will you use direct or indirect channels?
Promotion: Hypothetically, create a marketing communications campaign for this product.What promotion (communication) mix elements will you use and why? Where (what media) will you use to communicate your product? Explain why you’ve chosen this particular media type.
SWOT Analysis:Make a SWOT analysis for your product/service. Write 3 strengths, 3 weaknesses, 2 opportunities, and 2 threats.If you only write one word and do not provide any explanation next to it, I won’t be able to understand what you think.
Please write clearly

5. In 2016, over 42,000 people were killed by opioid overdoses. The effects of the issue are not limited to fatalities. An additional issue is the lack of proper development among young adolescent users during a critical phase of brain maturation. One method of reducing opioid abuse is to reduce the availability of prescription opioids. In 2010, 54 percent of students in 12th grade believed that prescription opioids were easily accessible. In a 2017 study, one agency surveyed three high schools in the northeast and found 266 of the 500 12th grade students surveyed believed prescription opioids were easily accessible in their community.
a. Is the above information sufficient for you to be certain that the percentage of all 12th graders who believe prescription opioids are easily accessible has declined? Why or why not?
b. In establishing a statistical hypothesis testing of this situation, give the required null and alternative hypotheses for a test to determine if the percent of 12th graders who believe opioids are easily accessible has declined from 2010.

H1:
c. Based on your answer in part b, should you use a right-tailed, a left-tailed, or a two-tailed test? Briefly explain how one determines which of the three possibilities is to be used.
d. Describe the possible Type I error for this situation--make sure to state the error in terms of the percent of 12th graders and their beliefs about opioid accessibility.
e. Describe the possible Type II error for this situation--make sure to state the error in terms of the percent of 12th graders and their beliefs about opioid accessibility.
f. Determine the appropriate critical value(s) for this situation given a 0.01 significance level.
g. Determine/calculate the value of the sample's test statistic.
h. Determine the P-value.
i. Based upon your work above, should you "Reject the null hypothesis" or "Fail to reject the null hypothesis?" Explain why.
j. Based upon your work above (and overlooking the flaws in the survey method), is there statistically sufficient evidence in this sample to support the claim that the percent of 12th graders who believe opioids are easily accessible has declined from 2010? Briefly explain your reasoning.
