Mba Business Statistics Case Study

At 5% level of significance, is there sufficient evidence to conclude that the proportions of errors in transactions assigned to each of the 5 memory locations are all different?

However, we must perform some analysis on this data to confirm that the results for our class really are significantly different from the average. To do this, we performed a chi-square analysis on our data. Our chi-square value is 14.733, and the degrees of freedom are 6. The resulting p-value falls between 0.05 and 0.02. Therefore, we conclude that the data from our class indeed does not fit the average.

Question 4 Use the following table to answer the questions that follow: According to the table, the labor force participation rate in this economy is equal to:

According to the website http://womenissues.about.com/cs/abortionstats/a/aaabortionstats.htm there are approximately 126,000 abortions conducted each day throughout the world. This website includes the abortion statistics of the world and breaks the data down to the demographics of the United States. It also discusses the decisions to have an abortion and the use of contraceptives in the United States. This was an informative website and included detailed statistics conducted by the Alan Guttmacher Institute. According to the website http://www.bls.gov/cps in 2000, gon average there were roughly 135 million employed and 6 million unemployed people in the labor force in the United States.h (p. 3) The websites definition of

You cannot analyze data until you have brought the relevant data that will answer the question you are asking. A new feature of Excel 2016 is the built-in function which makes getting and transforming your data much faster and easier and allows you to find and gather all your data into one place. These new capabilities were only available previously as a separate add-in called Power Query. Now they can be found built into Excel 2016. They can be accessed from the Get & Transform group located on the Data tab.

Analyze results - Graph the data from Table 4 and describe what your graph looks like (you do not have to submit a picture of the actual graph!).

There is no clear relationship between the two variables in the scatter plot. The points are in no specific pattern, suggesting that there is no significant correlation between the variables years and credit balance.

d. The percentage of the labor force that is out of work and the difference in average income from country to country

A histogram shows the distribution of data within the Income. In this Histogram graph of Income, it shows that the graph is not symmetrical. This histogram graph has a wider bell shape form. The graph shows that this graph is more like two graph because there is a clear difference between income generating

In these tables we are looking at the relationship between the race and how much education one have completed. Observing at the chi-square, the P-value of .000, which lies beneath the cut off .05. Since the P-value is less than .05, there is a statistical significant relationship between the notion of race and education.

In Peter Eavis’ article “Executive Pay: The Invasion of Supersalaries” the conflict of CEOs and top executives outrageous pay grade is discussed. Even though the “compensation machine” of Corporate America is running smoothly, there are multiple negative and dark undertones. In fact, many people believe that these shocking salaries are the roots of inequality within America. Currently, some CEOs are being compensated millions and millions of dollars as their normal annual salary. Even though the current executive compensation system focuses on performance and can “theoretically constrain pay,” there is nothing stopping the companies from giving their CEOs more. According to the Equilar 100 C.E.O Pay Study, “the median compensation of a

COMMENTS argument is that because the average effect size for published research was equivalent to that of a medium effect, the reviewer 's decision to reject the bogus manuscript under the nonsignificant condition was "reasonable." Further examination of the Haase et al. (1982) article and our own analysis of published research, however, demonstrates that the power of the bogus study was great enough to detect effect sizes that are typical of research published in JCP, which was our intention when we designed the bogus study. First, although the median effect size (if) for all univariate statistical tests, significant and nonsignificant, reported by Haase et al. (1982) was .083, this index was steadily increasing at a rate of approximately .5% per year, so that the projected median if- in 1981 (the year our study was completed) would be .13. Importantly, an r)2 of .13 corresponds to an effect size (/) of .39, which Cohen (1977) designates as a large effect. A further examination of the Haase et al. (1982) data also lends support to our argument. Their analysis examined the strength of association for 11,044 univariate statistical tests derived from only 701 manuscripts; thus, each manuscript reported an average of more than 15 statistical tests. Since statistically significant and

Q7: Create a bar graph or pie chart of the data you have collected. For example, you could create a bar graph that shows the employee turnover rate in organizations that do offer flexible work arrangement compared to organizations that do not. Alternately, you could create a pie chart that shows which types of flexible work arrangement workers want the most.
