I have asked my employees to pull and measure the amount of soda in each of thirty (30) randomly selected bottles off the line from all the shifts at the bottling plant. 1. The following calculations show the mean‚ median and standard deviation for the case study. Mean =14.8 The mean was calculated by getting the sum of total ounces in each bottle and then dividing that total by the sample size of thirty (30). Median = 14.8 The median is derived from the number that is in the middle‚ once the

Effects of Caffeine and Nicotine on Lumbriculus variegatus INTRODUCTION An experiment was conducted to study and explore the circulatory system by exposing Lumbriculus variegatus‚ black worms‚ to household drugs. Lumbriculus variegatus was chosen as the experimental organism because of their transparent bodies and their simple physiology. Their transparent bodies help the experimenters to easily see their pulse. Another reason for choosing this specific organism is their body structure—large

M & M Project Masterfoods USA put together a team to review the color a proportion of the M&M’s being placed in each 1.69 bag. To ensure that a random sample was obtained‚ each of the 20 members on the team acquired a bag of M&M’s from three different store locations. Each part of the project utilized the M&M’s obtained to determine if the color proportions are what the company expected to be in the bags. Additionally‚ the team identified a couple of process that could assist the company in

Statistical quality control (SQC) The application of statistical techniques to measure and evaluate the quality of a product‚ service‚ or process. Two basic categories: I. Statistical process control (SPC): - the application of statistical techniques to determine whether a process is functioning as desired II. Acceptance Sampling: - the application of statistical techniques to determine whether a population of items should be accepted or rejected based on inspection of a sample of those

is subjected to rapidly changing stimuli. Moreover‚ the theory states that after the detection of the first target in a rapid stream of visual stimuli‚ the second target is missed (Niewenstain‚ Potter‚ & Theeuwes‚ 2009). Hence‚ the experiment means to prove whether attentional blink is present in the experiment and if the theory is correct. Furthermore‚ the suggested hypothesis for this experiment is that the higher separation of the two targets with each other will increase the probability

Wally could also calculate the mean production forecast for each product and compare it to his own mean. This mean he calculates would also be an average of the product forecasts‚ but have him throw out the high and low forecasts in it. The closer his mean is to the Buying Committee would indicate an accurate forecast for the upcoming line as it has shown in the past. For conservatism’s sake
