A probability is generally defined as the chances or likelihood of an event occurring. It is calculated by identifying two components: the event and the sample space. The event is defined as the favorable outcome or success that we wish to observe.Sum of original 6 numbers = 20 × 6 = 120. Sum of remaining 5 numbers = 15 × 5 = 75. Number removed = sum of original 6 numbers – sum of remaining 5 numbers. Number removed = 120 – 75 = 45. Alternative Method: Let x be the removed number. The removed number is 45.

Linear Regression - Problems with Solutions Linear regression and modeling problems are presented along with solutions. Normal Distribution Definition .Mean median and mode are the three measures of central tendency. The mean is the value obtained by dividing the sum of the observations by the number of observations, and it is often called average. The median is the middlemost value in the ordered list of observations, whereas the mode is the most frequently occurring value. Q2. Find the mean, median, mode, and range for the following list of values: 1, 2, 4, 7. The mean is the usual average: (1 + 2 + 4 + 7) ÷ 4 = 14 ÷ 4 = 3.5. The median is the middle number. In this example, the numbers are already listed in numerical order, so I don't have to rewrite the list. But there is no "middle" number, because there are an ...Free Statistics Practice Tests.

We begin this problem with the knowledge that the mean of the first set is 20. Since that set contains five numbers, we know that its total sum must be 100 (since 100 divided by 5 is 20). so must be 25. Now, the only step left is to find the mean of .

Samples should be chosen randomly. Example: you ask 100 randomly chosen people at a football match what their main job is. Your sample is the 100, while the population is all the people at that match. See: Population.The z -score of 72 is (72 – 70) / 2 = 1. Thus we are looking for the area under the normal distribution for 1< z < 1.5. A quick check of the normal distribution table shows that this proportion is 0.933 – 0.841 = 0.092 = 9.2%.
