Statistics is the study of the collection‚ organization‚ analysis‚ interpretation‚ and presentation of data.[1][2] It deals with all aspects of this‚ including the planning of data collection in terms of the design of surveys and experiments. In mathematics‚ a graph is a representation of a set of objects where some pairs of the objects are connected by links. The interconnected objects are represented by mathematical abstractions called vertices‚ and the links that connect some pairs of vertices

A soft-drink machine is regulated so that the amount of drink dispensed is approximately normally distributed with a standard deviation equal to 1.5 deciliters. Find a 95% confidence interval for the mean of all drinks dispensed by this machine if a random sample of 36 drinks had an average content of 2.25 dl. 2.

Princess Faye N. Balatero Grade 8-Br. Edmund Hubert FSC Introduction: Statistics are used everywhere; we see statistics in use every day; statistics is used to answer important and practical questions. Statistics are useful in almost all disciplines. They are used in statistical analysis of results of an experiment‚ prediction of future values‚ growth and trend analysis‚ systematic presentation of data in the form of tables‚ diagrams and

investigate the effect of various parameters such as SNR‚ cyclic prefix/guard interval‚ number of subcarriers M‚ number of Monte-Carlo simulation loop nloop‚ type of modulation (qammod‚ pskmod) with different values of modulation levels q. Given the Matlab code that implements the OFDM system in AWGN channel‚ it is required to prepare a report that includes the following: 1. Study the effect of the length of the guard interval on the BER performance of the system. Provide one Matlab figure (Fig. 1)

9.18 a) Using forward stepwise regression to find the best subset of predictor variables to predict job proficiency. The Alpha-to-Enter significance level was set at 0.05 and the Alpha-to-Leave significance level was set at 0.10. The first predictor entered into the stepwise model is X3. SAS tells us that the estimated intercept is -106.13 and the estimated slope for X3 is 1.968. The R2-value is 0.8047‚ mean square error is 76.87. The second predictor entered into the stepwise model is X1.
