Study Aim to determine the effect of four different types of tips in a hardness tester on the observed hardness of a metal alloy. Four Specimen of the alloy were obtained, and each tip was tested once on each specimen, producing the following data

Tips specimen
1 9.3 9.4 9.6 10
2 9.4 9.3 9.8 9.9
3 9.2 9.4 9.5 9.7
4 9.7 9.6 10 10.2

a) Perform Anova using Minitab and present the table - please provide us with Minitab table?

b) is there an effect of the type of tips on the hardness.

c) Use fisher LSD to investigate the difference between the tips?

A Brinell hardness tester is used to determine the hardness of 1/2" thick steel plate. The specifications for the steel require that the steel have a tensile strength between 125 ksi and 150 ksi. A 3000 kg load is used for the test. A. Calculate the minimum and maximum Brinell hardness of the steel. B. If a hardness test reveals that the Brinell hardness of the steel plate is 260 BHN what is the diameter of the indention in the...

An experiment was performed to determine the effect of four different chemicals on the strength of a fabric. These chemicals are used as part of the permanent press finishing process. Five fabric samples were selected, and a randomized complete block design was run by testing each chemical type once in random order on each fabric sample. The data are shown in Table below. test for differences in means using an ANOVA with α=0.01 Fabric Sample Chemical Type 1 2 3...

In a study to compare the visibility of paints used on highways, four different types of paint were tested at three different locations. It is to be expected that paint wear will differ depending on the quantity and type of traffic on the road, so Highway was used as a blocking factor. The following table gives the amount of visibility of paint after a set period of exposure to traffic and weather; visibility was measured on a standard scale, with...

Researchers conducted a study to determine the effects of different types of alcohol on the peak alcohol concentration. In one part of the study, the researchers gave 15 randomly select males a controlled volume of vodka and monitored the subjects' alcohol concentration following the period of consumption. The legal limit for driving is 80 mg/dL (milligrams per deciliter of blood). A hypothesis test was conducted to see if the mean peak alcohol concentration from drinking vodka was different from the...

Case study: Deciding what is effective from different perspectives The aim of this case study is to illustrate the sometimes competing demands of effectiveness, efficiency and equity. In particular, it should help you to: Explain what is meant by key terms such as ‘LYG’, ‘QALY’ and ‘ICER’ Use these terms and the information they represent in a decision-making scenario ?        Compare and contrast the demands of effectiveness from different perspectives Scenario You are a member of an area prescribing...

Question 4 Researchers studied four different blends of gasoline to determine their effect on miles per gallon (MPG) of a car. An experiment was conducted with a total of 28 cars of the same type, model, and engine size, with 7 cars randomly assigned to each treatment group. The gasoline blends are referred to as A,B,C, and D.The MPGs are shown below in the table Gasoline Miles Per Blend Gallon A 26 28 29 23 24 25 26 B 27...
