Here: A = mid value of modal class n refers to the number of observations f is the frequency d = , where x is the average of the highest and lowest class interval, A is the mid value of the modal …

A data set can have one, two or multiple modes. A data set that has two modes is known as bimodal and the data set in which there are multiple modes is known as multi-modal data set. …

Hence, the interval notation of inequality is an open interval written inside parenthesis. It shows that -6 and 5 are not part of the solution. Here, -6 is the beginning of the interval and 5 is the …

Keep in mind that in each group, only the first value, or the lower limit, of the interval is included up until the value before the upper limit, or the last value, of the group. Meaning, while 0 is …

Now, let us take a point from the interval (-1, 1). Since f ' (x) <0, therefore the function is decreasing at this interval. Now, let us take a point from the interval and substitute it in the …

If the function is negative in a closed interval [a, b] then the graph of the function is below the horizontal axis. The area of the function can be defined like this: Now, let us solve some …

Here, a good width for the interval would be 8. This would give us 9 bins, which can be illustrated by the histogram below. Solution Problem 3. For this problem, you were asked to interpret the …

Table of Integrals What is Integration? Integration is an operation which helps you determine the area under the graph of a function. A B C Integral Integral sign Function Tells us which …
