A population is the total collection of objects that are of interest in a statistical study. A sample, being a subset, is typically smaller than the population. In a statistical study, all elements of a sample are available for observation, which is not typically the case for a population.Solution (C) is the correct answer. When each observation is multiplied by 2, then variance is also multiplied by 2. Example 9 A set of n values x 1, x 2, ..., x n has standard deviation 6. The standard deviation of n values x 1 + k, x 2 + k, ..., x n + k will be (A) σ (B) σ + k (C) σ – k (D)kσ Solution (A) is correct answer. Let us solve some questions based on conditional probability with detailed solutions. Question 1: Ten numbered cards are there from 1 to 15, and two cards a chosen at random such that the sum of the numbers on both the cards is even.A is the correct answer. Remember, in order to calculate the median, you must first order the values in the sample from lowest to highest. Doing so yields: 110 116 124 132 168 This sample is of size 5, and odd number, so the middle value of 124 is the sample median. 5. C is the correct answer. Here the sample mean, X = 64 inches, and the SD = 5 ...Solution (C) is the correct answer. When each observation is multiplied by 2, then variance is also multiplied by 2. Example 9 A set of n values x 1, x 2, ..., x n has standard deviation 6. The standard deviation of n values x 1 + k, x 2 + k, ..., x n + k will be (A) σ (B) σ + k (C) σ – k (D)kσ Solution (A) is correct answer. Standard Deviation Questions with Solutions. Steps to Find Standard Deviation. Step 1: Determine the mean of the observations, i.e. Arithmetic mean. Step 2: Calculate the squared deviations from the mean, i.e. (Data value – Mean) 2.
