Right Answer: Exploratory Data Analysis (EDA) is the process of analyzing and summarizing datasets to understand their main characteristics, often using visual methods. It helps identify patterns, trends, and anomalies in the data before applying formal modeling techniques.
Right Answer: 1. Remove duplicates
2. Handle missing values
3. Correct inconsistencies
4. Standardize formats
5. Filter out irrelevant data
6. Validate data accuracy
7. Normalize data if necessary
Right Answer: PROC MEANS creates the N (number of non-missing values) and NMISS (number of missing values) statistics, which are not created by PROC SUMMARY. Conversely, PROC SUMMARY does not create the standard deviation (STD) and variance (VAR) statistics if the output dataset is specified, while PROC MEANS does.

Company used to have a monopoly however deregulation had allowed for competition starting 10 years ago and the firm now had 40% market share. Firm had four plants, two made mostly flat steel products and two made pipe like steel products. For all plants half the products were specialized and half were standard. What should be done to solve the problems?
Right Answer: The company should implement a demand forecasting system to better align production with customer needs, streamline operations to reduce lead times, improve inventory management to minimize excess stock, and enhance customer service to address complaints.

Ques:- I was sitting in one of Chicago’s new specialty ‘Cigar Bars’ around the end of August with a friend. It was a Saturday night and the weather was fair. While enjoying one of the bar’s finest stogies and sipping a cognac, I asked my friend how much he thought the bar was worth. On the back of the envelope, how would you go about determining the value of this bar?
Right Answer: To determine the value of the cigar bar, consider the following steps:
1. **Revenue Estimation**: Estimate the bar's annual revenue by analyzing average customer spend, foot traffic, and peak hours. Multiply the average spend per customer by the estimated number of customers per day and then by 365 days.
2. **Cost Analysis**: Calculate the annual operating costs, including rent, utilities, staff salaries, inventory, and other expenses.
3. **Profit Calculation**: Subtract the total annual costs from the total annual revenue to find the net profit.
4. **Valuation Multiple**: Use a valuation multiple (often based on industry standards, such as a multiple of earnings before interest, taxes, depreciation, and amortization - EBITDA) to estimate the bar's worth. A common multiple for bars might range from 3 to 5 times the net profit.
5. **Market Comparison**: Research recent sales of similar establishments in the area to validate your estimate and adjust based on
Ques:- Soybeans are a commodity product. A soybean manufacturer, which processes soybeans for food and energy. 80% of production is for food, 20% is for energy. The soybeans are processes in North America, but majority of energy demand today is in Asia/Pacific. The CEO has hired you to understand what is the most efficient method of delivering the product to Asia. You need to decide whether to process all in North America and then ship to Asia/Pacific, or ship raw to Asia/Pacific and then process.
Right Answer: To determine the most efficient method of delivering soybeans to Asia/Pacific, you should conduct a cost analysis comparing the expenses of processing in North America versus shipping raw soybeans for processing in Asia/Pacific. Consider factors such as transportation costs, processing costs, tariffs, and demand in the target market. If processing in North America and shipping is cheaper overall, choose that option; if shipping raw soybeans and processing in Asia/Pacific is more cost-effective, opt for that.

This layout maximizes customer flow and encourages purchases.
Right Answer: Key metrics to determine the ongoing success of a project include:
1. **Schedule Variance (SV)** - Measures if the project is on schedule.
2. **Cost Variance (CV)** - Assesses if the project is within budget.
3. **Quality Metrics** - Evaluates the quality of deliverables against standards.
4. **Stakeholder Satisfaction** - Gauges the satisfaction of stakeholders and team members.
5. **Scope Change** - Tracks any changes to the project scope and their impact.
6. **Risk Management** - Monitors identified risks and the effectiveness of mitigation strategies.
7. **Resource Utilization** - Measures how effectively resources are being used.
