MATH 114 Liberty University Standard Deviation Project Excel Sheet
Project 1 Instructions Please also pay close attention to any additional specifications provided by your professor. Professors often will clarify their expectations regarding the format and presentation of your submission. The Range Rule of Thumb is based on the insight that the range is often approximately 4 times as large as the standard deviation. This insight enables you to quickly estimate the standard deviation of a data set by finding the maximum and minimum data values, using them to compute the range, and then dividing this value by 4. Each of the following 5 data sets has a mean close to 100, and a standard deviation in the 20s. Assume that each of these are sample data sets. For each of the 5 data sets given below, use the Excel function “=stdev.s” (or technology) to find the actual sample standard deviation (10 points), compute the estimate given by the Range Rule of Thumb (RROT) Estimate (10 points), and compute the percentage error of the estimate (10 points). The formula for the RROT estimate is RROT estimate = Range/4 (where the range = maximum value – minimum value), on the assumption that the Standard Deviation » RROT estimate. The formula used to find the percentage error of the estimate is: Summarize what you learned: % Error = | RROT Estimate – Standard deviation | / Standard Deviation × 100 = ____ % .

BU Mathematical Quantitative Reasoning Increment in Knowledge Discussion
Question 1Prompt: Give two examples of large sets. Then, describe either their
union or intersection. For example, set A = animals in Mississippi and
set B = marsupials. Then, A intersect B = {opossum}. When responding to a
classmate, if they provided the union of their examples, describe the
intersection and vice versa. For example, A union B is the set of all
animals in Mississippi and all marsupials. So, kangaroos are in this
set.Requirements: 250 words minimum initial post, 100 words minimum replyQuestion 2Prompt: How can passages such as Proverbs 1:5 motivate a student in a

CU Educational Attainment Differences in First & Second Gen Hispanics & Asians Discussion
In this chapter, we examined the difference in educational attainment between first- and second-generation Hispanic Americans and Asian Americans based on the proportion of each group with a bachelor’s degree. We present additional data from the Pew Research Center’s 2013 report, measuring the percentage of each group that owns a home (Frankfort-Nachmias, & Leon-Guerrero, 2018, p. 231).First-Generation Hispanic Americans (N = 899), 43% own a homeSecond-Generation Hispanic Americans (N = 351), 50% own a homeFirst-Generation Asian Americans (N = 2,684), 58% own a homeSecond-Generation Asian Americans (N = 566), 51% own a homeSource: Pew Research Center, Second-Generation Americans: A Portrait of the Adult Children of Immigrants.

Is there a significant difference between first-and second-generation Hispanic American populations?
Yes
No
Question 2 3 Points What is the difference? -2.33 2.33 0.0198 0.07 Question 3 2 Points Is there a significant difference between first-and second-generation Asian populations?

Question 4 2 Points What is the difference? 3.50 -3.50 0.0004 0.07
In 2016, the Pew Research Center surveyed 1,799 white and 1,001 black Americans about their views on race and inequality. Pew researchers found “profound differences between black and white adults in their views on racial discrimination, barriers to black progress and the prospects for change.” White and black respondents also disagreed about the best methods to achieve racial equality. For example, 34% of whites and 41% of blacks said that “bringing people of different racial backgrounds together to talk about race” would be a very effective tactic for groups striving to help blacks achieve equality.Test whether the proportion of white respondents who support this tactic is significantly less than the proportion of black respondents.

We compare the proportion who indicated that it was “very important” to be born in this country to be American for two GSS 2014 groups: respondents (1) born in the United States (native born) and (2) not born in the United States (foreign born). Test the research hypothesis that a higher proportion of native-born respondents than foreign-born respondents indicated being born in the United States was “very important” to be American. Set alpha at 0.05.

weight loss program, weights of 40 subjects are recorded, statistics homework help
In a test of a weight loss program, weights of 40 subjects are recorded before and after the program. Assume that the before/after weights result in r = 0.876.Is there sufficient evidence to support a claim of a linear correlation between before/after weights?Does the value of r indicate that the program is effective in reducing weight? Why or why not?1 paragraph
