Proposed Plan: Survey: Type of research is investigative research and total Population is almost 5000 customers. The total sample size is selected 350 customers IBBL and some staffs that is not selected yet. Most of the data is collected by the primary data with a survey of close ended questions. Some secondary data is collected from different documents like Financial report‚

Statistics Coursework Plan – In this project‚ I will be investigating how accurately students can estimate an angle size and the length of a line. I am investigating it to see if age‚ gender and mathematical capabilities have an effect on how accurate students can estimate a length of a line and an angle size. I will be using secondary raw data which is given to me to my teacher who has collected the data from other students. The accuracy of the data is unknown and also human errors are also

about sampling and statistical procedures that can be used to control their manufacturing process. Their client has offered samples to be analyzed‚ so they can quickly learn whether the process is operating satisfactorily or corrective actions needs to be taken. The numbers given in the case were as follows: assumed population standard deviation is equal to .21‚ sample size is equal to 30 and the test value of the mean was 12. They also stated the two hypotheses to be tested: the null hypothesis

distribution refers to a frequency or probability distribution of the sample statistic obtained from all the possible samples of size n taken at random from a given population. The sample mean (x) shows the average value calculated from measurements of a sample. Its main characteristics are: 1. The average of all sample means should equal to the true population mean (µ) 2. The standard deviation shows dispersion of sample means around the population mean. It is known as the standard error

Introduction Now that we have determined the procedures to be performed‚ we are ready to select and evaluate a sample. 2. Objective of tests (review) a. Tests of control - determine if control is effective for purposes of assessing control risk and determining likelihood of error in financial statements. b. STOT - Determine existence of monetary errors

control called statistical process control that will ensure my morning process is effective. One method of quality control can be pursued through process control procedures like statistical process control or SPC. SPC “involves testing a random sample of output from a process to determine whether the process is producing items within a preselected range”. (Chase‚ Jacobs & Aquilano‚ 354) SPC is a method that can be applied to a process in order to monitor or control that process. In week one

current models were subjected to distance test. The testing was performed with a mechanical hitting machine so that any difference between the mean distances for the two models could be attributed to a difference in the two models. Based on the sample studied of 80 golf balls both current and new models‚ I have done the following analysis: 1. Formulated a hypothesis test for Par’s comparison of the driving distances of the current and new golf balls. 2. Analyzed data to provide a hypothesis
