Calculate the least squares (best–fit) line. Put the equation in the form of: ŷ = a + bx. Find the correlation coefficient.Questions and their Solutions Question 1 A die is rolled, find the probability that an even number is obtained. Solution to Question 1 Let us first write the sample space S of the experiment. S = {1,2,3,4,5,6} Let E be the event "an even number is obtained" and write it down. E = {2,4,6} We now use the formula of the classical probability.
21. Take a simple random sample from each group. One way is by assigning a number to each patient and using a random number generator to randomly select patients. 23. This would be convenience sampling and is not random. 25. Yes, the sample size of 150 would be large enough to reflect a population of one school. 27.Consider statistics as a problem-solving process and examine its four components: asking questions, collecting appropriate data, analyzing the data, and interpreting the results. This session investigates the nature of data and its potential sources of variation. Variables, bias, and random sampling are introduced. View Transcript.

Modeling foreign exchange rates with jumps. 2007 •Using the empirical rule, you would expect 95 percent of the values to be within two standard deviations of the mean. Using the formula for the standard deviation is for a sample sum: so you would expect 95 percent of the values to be between 5,000 + (2) (44.3) and 5,000 – (2) (44.3), or between 4,911.4 and 588.6. 86.The answer to a subtraction problem is called the difference. The value being subtracted is called the subtrahend, and the value from which the subtrahend is being subtracted is called the minuend.MAS3301 Bayesian Statistics Problems 1 and Solutions Semester 2 2008-9 Problems 1 1.
