For example, consider a random variable X which follows a binomial distribution with parameters n = 50 and p = 0.2. Here “n” is the number of trials, and “p” is the probability of success. Its notation can be written as X-B(50,0.2), and imaging the question asks to find P(X>9), which is the probability of X taking a value greater than 9.

Advanced statistical calculations: tests (Z-test, t-test, χ²-test, F-test, ANOVA), intervals (Z-interval, t-interval), distributions The fx-CG50 is our most advanced graphic calculator approved by exam boards. Its functionality is a perfect fit from GCSE to A-level Maths, Further Maths and IB. The user-friendly icon menu, function keys and interactive format enable intuitive operation. The large high-resolution colour screen gives exceptional clarity and easily distinguishes different graphs. The Test mode on the fx-CG50 calculator is useful for performing hypothesis test questions. To explore it, find a normal distribution hypothesis test from any UK A-level mathematics exam syllabus and then go to Statistics Mode (MENU 2) and then F3 (TEST), F1 (Z), F1 (1-Sample) and F2 (Var) and input the relevant parameters from the question. If studying further Mathematics or Statistics A-level then there are several options here that are also useful (e.g. Chi-squared tests, t-tests, ANOVA tests etc. ). If you require any further information relating to the Delivery service used, please call us at +44 (0)20 8208 9567.The history feature means you can do a calculation and then do another calculation with that answer. However, unlike on scientific calculators there is more than one line of input shown, meaning you can expand or amend a series of calculations further and even go off the screen – you can keep scrolling down, and you’re not limited to the space shown on the screen. Exploring graph mode Applications for CG50A can be made online in myAccountor the Revenue Online Service (ROS)by selecting: graphs, 20 graphing functions, spreadsheet function, statistical function, dynamic graphing, geometry, picture plot, integral graphing, pie & bar chart (in stat mode), graphing calculations, linear, quadratic and cubic equations, vector analysis, mathematical functions, square root, fractions, integration, complex functions, matrix algebra, linear equations, polynomial equations

Whether wanting to learn about the main functions of the fx-CG50 graphic calculator, solve polynomials or simultaneous and trig equations – our vast suite of resources provides all the support you need to teach using Casio calculators. Knowing these two views is useful because sometimes you may need a decimal because it’s asked for in a question, or sometimes you use the fraction because that’s an exact answer.

E-CON4 Application

You may want to graph a function because you want to analyse it. You would then use Graph Solve or G-SOLVE. The most common aspects you may want to explore on your graph include finding the root, it’s local maximum value or its local minimum value, where it is crossing the y-axis. or, if there are two functions drawn, where they cross each other. Both Test mode and SolveN can be powerful tools for analysing data and making statistical inferences in a variety of fields. Book a training
