Tutorial 4: Estimations 1. A process producing bricks is known to yield output whose weights are normally distributed with a standard deviation of 0.12lb. A random sample of 40 bricks from a day’s output had a mean weight of 4.07lb. (i) Find a 99% confidence interval for the mean weight of all bricks produced on that day. (ii) Estimate the smallest sample size required if the error in estimating the population mean weight of all bricks is to be within 0.03lb with 95% confidence.

On Measuring Available Bandwidth in Wireless Networks Andreas Johnsson Research Area Packet Systems Ericsson Research Mats Björkman The Department of Computer Science and Electronics Mälardalen University Abstract— BART is a state-of-the-art active end-to-end bandwidth measurement method that estimates not only the available bandwidth but also the link capacity of the bottleneck link. It uses a Kalman filter to give estimates in real time during a measurement session. In this paper‚ we have studied

Exercise #3 1. If I were in Lauren’s shoes‚ I would make sure it’s clear to the strategic management group that my estimate – a more detail/micro estimate – came in well over their initial macro estimate. That being said‚ I would also provide upper management with the ideas (outsourcing‚ change scope‚ cancel project..) developed with stakeholders in the brainstorming meeting. Simply moving forward with the project after finding such a large gap in estimates would be a terrible idea that would

Latin square design(Lsd): In analysis of varianc context‚ the term “Latin square design” was first used by R.A Fisher. Latin square design is a design in which experimental units are arranged in complete blocks in two different ways‚ called rows and columns and then the selected treatments are randomly allocated to experimental units within each row and each column. Such that each treatment appears exactly once in each row and once in each column. Since this design is a square arrangement where
