Question

Build a Matlab Program to perform this operation As an engineer, you must be able to analyze data sets using some kind of statistical analysis. You will need to create a function that will do both of the following: If only provided a single data set, create a confidence interval on the average given the values defined by the user and a t value based on the number of samples and the level of confidence (p =0.001, 0.05, 0.1) If the user inputs two data sets, perform a Student’s two-sample t-test to detect if there is a difference in the means. The table for t-values you should use is posted to OnCourse under the Project Details Resources page. Your program only need accommodate for up to 26 samples. Useful equations below. For Confidence Interval… x_bar = average s = standard deviation n = number of samples = n – 1 = Significance level (0.001, 0.05, 0.1) In this case, t is taken from your table For Two-Sample T-Test This calculated t-value is compared against the critical t-value obtained using = n1 + n2 – 2 and your level of significance. If the absolute value of your calculated t-value is larger than the t-value you have obtained from your table, it is said that the two samples are statistically different. Your function call should look something like below… x = statsT(0.05, DATA1) - which returns something like…. x = (3.2596, 4.7135) x = statsT(0.05, DATA1, DATA2) - which would in turn give… x = 0 or x = 1 (Note that this t-test should only return whether these samples are different) Be sure to handle the output of the function in a way that can be understood by the user. Notes: the MATLAB function ‘exist’ will likely be useful in this problem. The csv file posted to OnCourse is in NO WAY the data set you are using for the problem. This table is simply used for solving for a t-value based on the alpha and number of samples. The set of data you use should be a single row/column vector of numbers. For instance, you could say DATA1 = 1:10 and DATA2 = 10:20. However, you should test with values that might create both situations of true and false for the t-test.

Explanation / Answer

Various SDLC methodologies are developed to guide the processes concerned, as well as the body of water model (which was the initial SDLC method); speedy application development (RAD); joint application development (JAD); the fountain model; the spiral model; build and fix; and synchronize-and-stabilize. Frequently, many models square measure combined into some form of hybrid methodology. Documentation is crucial notwithstanding the sort of model chosen or devised for any application, and is typically drained parallel with the event method. Some strategies work higher for specific varieties of comes, however within the end, the foremost vital issue for the success of a project could also be however closely the actual set up was followed.

In general, AN SDLC methodology follows the subsequent steps:

The existing system is evaluated. Deficiencies square measure known. this will be done by interviewing users of the system and consulting with support personnel.
The new system needs square measure outlined. specifically, the deficiencies within the existing system should be self-addressed with specific proposals for improvement.
The projected system is intended. Plans square measure set out regarding the physical construction, hardware, in operation systems, programming, communications, and security problems.
The new system is developed. The new elements and programs should be obtained and put in. Users of the system should be trained in its use, and every one aspects of performance should be tested. If necessary, changes should be created at this stage.
The system is place into use. this will be drained numerous ways in which. The new system will phased in, in step with application or location, and also the previous system bit by bit replaced. In some cases, it should be less expensive to finish off the previous system and implement the new system all right away.
Once the new system is up and running for a jiffy, it ought to be thoroughly evaluated. Maintenance should be well-kept strictly in the slightest degree times. Users of the system ought to be unbroken up-to-date regarding the most recent modifications and procedures.

   obtaining started with the systems development life cycle
To explore however the systems development life cycle is employed within the enterprise, here square measure some extra resources:
Varying SDLC methodologies among development teams: software package development life cycle (SDLC) methodologies have their own benefits, tools then forth. professional David Christiansen explains why development teams ought to be allowed to embrace a range of methodologies.
How use cases facilitate the SDLC: Why incorporate use case techniques into your software package development lifecycle? needs professional Betty Luedke explains however use cases profit the SDLC and the way practitioners will get the foremost out of them
When to start testing within the SDLC: Testing is one in every of the foremost vital elements of the software package development lifecycle, however once to start testing depends on variety of things. professional microphone Kelly discusses however bound problems have an effect on the temporal order of testing within the SDLC.
