Attach ToothGrowth in package datasets. What is the description of this data? (a) How can you inspect the structure of the data to show the first few parts of this data?. (b) The following is a sample from the ToothGrowth data. Describe how this data can be obtained and named Tooth. 2mg. len supp dose 23.6 VC 18.5 VC 33.9 VC 25.5 VC 2 26.4 VC 2 32.5 VC 26.7 VC 21.5 VC 23.3 VC 29.5 VC 25.5 OJ 26.4 OJ 22.4 OJ 24.5 OJ 24.8 OJ 30.9 OJ 26.4 OJ 2 27.3 OJ 29.4 OJ 23.0 OJ (c) Obtain descriptive statistics for Tooth length due to each Supplement type. (d) Construct a histogram for each sample and comment on the distribution. Superimpose the density curve of the data on your histogram. Would you agree to the assertion that both are approximately normally distributed? (e) Are there any outliers in the data? (f) Are the means of the tooth lengths due to each Supplement type (VC or OJ) different? Test at 4% significant level. (g) Comment on your results

Which architectural design pattern is most suitable for computer systems in which one component is responsible for the generation of data? You are need to offer two examples taken from the actual world in order to validate your finding of a pattern. If you so want, you may additionally submit a snippet of code that describes the process that was used to uncover the pattern.
Assume you are in charge of compiling the information from books. Either more books should be placed on the shelf, or the books already on one side of the shelf should be removed. Choose and explain the best data structure for this situation. Give a flexible answer on how to add books to the shelf. What happens when a data structure has to be updated with new information but has insufficient space?
How would you handle an imbalanced dataset?
Using the images of the dataset below, please answer the following questions NOTE: All answers should be supported by coding and/or some written discussion. 1. Explain what this dataset about?Hint: You may need to look at columns, rows, and cells to understand the dataset. 2. Define the neighbor hood and the year where was the biggest square feetHint: You may use .max() method 3. Is there is any relation between the income and the square feet?Hint: You may need to draw (plot) your dataset. 4. For each minimum net income in the dataset, what was the years?Hint: You may use grouped and aggregated calculations 5. Reshape the dataset based on units and value.Hint: You may apply tidy data approaches
