In a test of differences between proportions, two samples are taken. In the first sample, a sample size of 100 shows 25 successes. In the second sample, a sample size of 80 shows 25 successes. What would be the value of B in this case?
List I List II Sampling techniques used in research Description A. Simple random sampling I. The units are identified in terms of various specific features identified before drawing a sample structure B. Systematic sampling II. Each unit is given an equal independent chance of being picked up C. Dimensional sampling III. The k – interval is obtained by N/n and the units are drawn using the same, where N is population size and n is desired sample size. D. Snowball sampling IV. First member unit is used to identify the second unit and so on   Choose the correct answer from the options given below:
Validate the statement: “For a given image in one-dimension given by function f(x, y), to sample the function we take equally spaced samples, superimposed on the function, along a horizontal line. However, the sample values still span (vertically) a continuous range of gray-level values. So, to convert the given function into a digital function, the gray-level values must be divided into various discrete levels.”
Consider the following C function in which size is the number of elements in the array E: int MyX(int *E, unsigned int size) {       int Y = 0;       int Z;       int i, j, k;       for(i = 0; i < size; i++) Y = Y + E[i];       for(i = 0; i < size; i++) for(j = i; j < size; j++) {       Z = 0;       for(k = i; k <= j; k++) Z = Z + E[k];       if (Z > Y) Y = Z; }       return Y; } The value returned by the function MyX is the
A bag contains 10 marbles out of which 3 are red and the rest are blue. In how many ways can a random sample of 6 marbles be drawn from the bag so that at the most 2 red marbles are included in the sample and no sample has all the 6 marbles of the same colour?
