The Baker Company wants to develop a budget to predict how overhead costs vary with activity levels. Management is trying to decide whether direct labor hours (DLH) or units produced is the better measure of activity for the firm. Monthly data for the preceding 24 months appear in the file P13_40.xlsx. Use regression analysis to determine which measure, DLH or Units (or both), should be used for the budget. How would the regression equation be used to obtain the budget for the firms overhead costs?
An Annotated/labeled data pool is an important asset for a data scientist. The more annotated data you can gather, the better your model estimations become towards the unknown variables. A team of data scientists is going to label a new dataset for both future use and the improvement of your current model estimates. They started by recording the amount of time it takes to label one record of data, and found that it took on average 5 minutes for them to do so. They also noted that there is a standard deviation of 5 minutes for the recording time as well. They are allowed to spend 4 hours per day this week (only Monday to Friday) to perform this annotation task. Please find out at most how many records would be labelled by the team in a single week with a probability of at least 97.5%?
ASQ (The American Society for Quality) Defines a Six Sigma project as: Six Sigma is a method for reducing variation in manufacturing, service, or other business processes. Six Sigma projects measure the cost benefit of improving processes that are producing substandard products or services. Whether in manufacturing or service industries, such projects quantify the effect of process changes on delays or rework. The goal of each successful Six Sigma project is to produce statistically significant improvements in the target process; over time, multiple Six Sigma projects produce virtually defect-free performance. The Six Sigma Black Belt project is one that uses appropriate tools within a Six Sigma approach to produce breakthrough performance and real financial benefit to an operating business or company. The tools are generic. It is the structure of the project and the associated process (improvement model) that distinguish a Black Belt project from other similar quality improvement…
can you help me answer this questions: 1-A moving average is the average of the observations in the past few periods, where the number of terms in the average is the span. True False 2- All nominal data may be treated as ordinal data. False True 3 - Phone numbers, Social Security numbers, and zip codes are typically treated as numerical variables. True False 4 - Correlation is useful only for: a.measuring the strength of a linear relationship. b.conveying the same information in a simpler format than a scatterplot. c.measuring the strength of a nonlinear relationship. d.assessing the weakness of a linear relationship. 5 - Which of the following will give the value for the third quartile? a.

Choose all answers that form a true statement: “When performing Savitzky–Golay polynomial smoothing, increasing the number of data points used to perform the smoothing can result in …”: a. spectral distortion b. noisy data c. a decrease in the number of points in the data set. d. a shift in the data points to the right. For each option above (a-d) that forms a true statement, explain why it is true and what the ramification is for using smoothed data to interpret the behavior of the chemical system under study.

Good Afternoon Please help me to respond to this question please view the two figures 1.1a and 1.1b in this order attached to this question and taking them as the subject matter in discussion and please awnser the below question. 2. Comment briefly on the advantages and disadvantages of a “ratio scale”.Your answer should focus primarily on what you can learn from the two different versions of the chart.Please use some simple maths to explain your answer. All data necessary of these graphs is present in following link: https://ourworldindata.org/grapher/historys-hockey-stick-gross-domestic-product-per-capita-using-the-ratio-scale-1990?tab=chart&stackMode=absolute&region=World I believe this is all that is necessary to complete this so I am submitting it now hope you have a Happy New Year!
Rajan wanted a radio from Jacky's. It appears that Rajan is particularly interested in purchasing a Radio from the inexpensive retailer's sales manager for consumer electronics. He tells Jacky, the salesperson at the inexpensive store where he thinks he'll get the best deal, that his old radio died and he wants to listen to his favourite tunes. He wants a replacement radio as quickly as possible. In three and a half weeks, Rajan's favourite model will be 10% off.He suspects Rajan won't wait and will find another job. Jacky will earn less on the lowered price. He thinks that telling Rajan of the sale makes little sense.When Jacky tells Rajan that the radio set he wants is no longer available and won't be for another week, Rajan is enraged. Fearing losing the business, Jacky begs his sales manager, Michelle, to speed up delivery. Michelle says it's impossible and suggests Jacky tell Rajan the store can get the set in 24 hours and sell him the demo model. Michelle says the sample is new…
