A study of parental empathy for sensitivity cues and baby temperament (higher scores mean more empathy) was performed. Let x1 be a random variable that represents the score of a mother on an empathy test (as regards her baby). Let x2 be the empathy score of a father. A random sample of 37 mothers gave a sample mean of x1 = 69.72. Another random sample of 29 fathers gave x2 = 59.51. Assume that σ1 = 12.32 and σ2 = 11.55.
(a) Let μ1 be the population mean of x1 and let μ2 be the population mean of x2. Find a 95% confidence interval for μ1 – μ2. (Use 2 decimal places.)
| lower limit | |
| upper limit |
(b) Examine the confidence interval and explain what it means in the context of this problem. Does the confidence interval contain all positive, all negative, or both positive and negative numbers? What does this tell you about the relationship between average empathy scores for mothers compared with those for fathers at the 95% confidence level?
Because the interval contains only positive numbers, we can say that the mothers have a higher mean empathy score.Because the interval contains both positive and negative numbers, we can not say that the mothers have a higher mean empathy score. We can not make any conclusions using this confidence interval.Because the interval contains only negative numbers, we can say that the fathers have a higher mean empathy score.

Dumping
Business Case Problem 11-4, Page 228
Nuclear power plants use low-enriched uranium (LEU) as a fuel. LEU consists of feed uranium enriched by energy to a certain assay--the percentage of the isotope necessary for a nuclear reaction. The amount of energy required is described by an industry standard as a "separative work unit" (SWU). A nuclear utility may buy LEU from an enricher, or the utility may provide an enricher with feed uranium and pay for the SWU's necessary to produce LEU. Under an SWU contract, the LEU returned to the utility may not be exactly the uranium the utility provided. This is because feed uranium is fungible and trades like a commodity (such as wheat or corn), and profitable enrichment requires the constant processing of undifferentiated stock. Foreign enrichers, including Eurodif, S.A, allegedly exported LEU to the United States and sold it for "less than fair value." Did this constitute dumping? Explain. If so, what could be done to prevent it? [United States v. Eurodif, S.A., 555 U.S. 305, 129 S.Ct. 878, 172 L.Ed.2d 679 (2009)] (Cross & Miller, 2018, p. 228)

For this discussion, you are tasked with finding an article or television segment discussing either a US or foreign policy change that is having some type of impact on the manufacturing process, price of goods and employment rates in the US. I am going to ask that you only look at this discussion in terms of policy and not through the often-divisive lens of politics. Please copy and paste your article into the discussion forum or the link if it is a television segment. Additionally, please summarize what the policy is that is being discussed and how it is impacting manufacturing in this country.
