MT230 2010/2011 Exercise 1 (To be returned on Tuesday‚ October 5) Question 1 A mechanical jar filler is used to fill jars with coffee. The filler is set so that the mean jar fill is 205 grams. The standard deviation of the jar fills is 2.5 grams. If the population of jar fills is normally distributed‚ what percentage of jar fills will be (i) greater than 202.5 grams‚ (ii) between 201.25 and 208.75 grams‚ and (iii) greater than 212.5 grams? If coffee jars have a capacity of 200 grams‚ (iv) what percentage

The Math lab evaluation Have you ever been to a place that is depressing‚ gloomy‚ and absolutely apathetic? If not then by all means make a point to go by and visit the math lab. As a student of the University of South Alabama I have been asked to evaluate the math lab by my supervisor. My supervisor had received various complaints by students‚ for that reason I have been asked to observe the math lab record what I saw and write down any suggestions for change. During this evaluation I will discuss
