Fast Food AnalysisFor the purposes of Questions 10 to 19, we are interested in trying to predict the number of calories in fastfood items, given otherinformation about their nutritional content. You will need to open Rstudio, and then write and run some code, in order to answer thesequestions. You should attach the .r file used to answer these questions to your submission. Whilst not directly used for assessment, it maybe used as evidence in the case of a marking dispute, as well as evidence of plagiarism should it be necessary.Before you start, you will need to install the openintro library viainstall.packages ("openintro")Then, load library openintro and look at the help file for fastfood.library ("openintro")?fastfoodPlease let me know (by email) sooner rather than later if you have technical issues installing the package and loading thedata.Now, we are going to be interested in a subset of this data. Start by generating a new dataframe ffood that you are to use throughoutthese questions as follows:fries <- fastfood [,-c (1, 2,4,7,17)]burger <- which ( rowSums ( is.na ( fries ) ) > 0 )ffood <- fries [-burger, ]sum ( is.na ( ffood ) ) Question 16Use 200 replications of data-splitting with 230 samples for training to compare the predictive performance of the following modelswith the remaining possible predictors for calories.- Best subset selection (BSS) with BIC (you may use the predict.regsubsets function introduced in the practical demonstrationby copying the code and pasting into your R script).- Ridge with min-CV lambda (use 5 or 10 folds).- PCR with min-CV number of principal components.Display the results in the form of boxplots. Using this plot, or otherwise, select which of the following options represents the medianCV predictive performance (in terms of test correlation) ranking from highest to lowest.At the start of your code for this question, it is recommended that you set the random seed to 3 usingset.seed (3)for reproducibility purposes.BSS, ridge, PCR(B) ridge, BSS, PCRC) PCR, ridge, BSSD PCR, BSS, ridgeE BSS, PCR, ridgeF) ridge, PCR, BSSQuestion 17Following on from Question 16, re-run your code (including setting the seed), this time storing the number of variables chosen foreach of the 200 replications of Best Subset Selection, and display the results in a histogram. How many predictors does a modelchosen by Best Subset Selection favour most frequently?Add your answerQuestion 18Following on from Questions 16 and 17, re-run your code (including setting the seed), this time storing the number of principalcomponents chosen for each of the 200 replications of PCR. What is the mean number of principal components chosen acrossthese 200 replications?Add your answer

The following Form is same as 2nd example of lecture 17 with 2 additional button "Fetch" and "Reset" remaining button functionality remains same. Table name is product with column ID,Name and Price. User enter ID and click on Fetch button, it will get record from Database against the given ID and display Name and Price and disable ID text box and also disable Insert button. So user can update or delete the fetched record. On reset it will bring the form and fields on normal state. You have to implement all button functionality.

You have a list of all your contacts details that you would like to store in a database. Your goal is that when a record is inserted in contacts table, you also want this record to be stored (inserted) in a backup table. Assume you have the two tables created: CONTACTS and CONTACTS_BACKUP. These two (2) tables have the same records. The CONTACTS table have the following columns: CONTACT_ID (Primary_Key), FIRSTNAME, LASTNAME and MOBILE_NO.
