Part 5 Question 4A study was carried out to determine whether the resistance of thecontrol circuits in a machine are lower when the machine motor isrunning. To ivestigate this question, a set of the control circuits wastested as follows. Their resistance was measured while the machinemotor was not running for a certain period of time and then againPage 4while the motor was running. The values found are listed in worksheet'Dataset4', with kilo-Ohms as the unit of measurement.1. Set up the structure of an appropriate statistical test to determinewhether the resistance of the control circuit in a machine is lowerwhen the machine motor is running.2. Explain how the order of subtraction chosen to calculate the dif-ferences will influence the structure of the test.3. Give a reason why the data is measured with the engine not run-ning first and then with the engine running.4. Explain how knowing the mean of the differences in advancewould influence the structure of your statistical test.5. Carry out the statistical test and state your conclusions.

A study was carried out to determine the influence of a trace elementfound in soil on the yield of potato plants grown in that soil, defined asthe weight of potatoes produced at the end of the season. A large fieldwas divided up into 14 smaller sections for this experiment. For eachsection, the experimenter recorded the amount of the trace elementfound (in milligrams per metre squared) and the corresponding weightof the potatoes produced (in kilograms). This information is presentedin the worksheet ‘Dataset5’ in the Excel document. Define X as thetrace element amount and Y as the yield.1. Draw a scatterplot of your data set.Page 52. Calculate the coefficients of a linear equation to predict the yieldY as a function of X.3. Calculate the correlation coefficient for the paired data values.4. Set up the framework for an appropriate statistical test to establish if there is a correlation between the amount of the trace element and the yield. Explain how having the scatterplot referredto…
A factory deep in a fjord has over a long time released a certain type of heavy metal, and a mappingof the concentration of the heavy metal on the seabed in the area around the factory has been carried out. It's for eachsample recorded heavy metal concentration, distance to the factory (in km) and depth (in meters). You findthe data in the file Heavy metal data.We will initially look at the connection between heavy metal concentration and distance to the factory,and fit a linear regression model Y = α + βx + e where we use heavy metal concentration asY -variable and distance as x-variable.1.) Briefly explain why it is reasonable to use heavy metal concentration as the Y variable and distanceas x-variable and not the opposite.2.) Give practical interpretations of the α-parameter and the β-parameter in the model in this situation.2.) What does it mean in practice in this specific situation if β < 0, if β = 0 and if β > 0?

A photoconductor film is manufactured at a nominal thickness of 25 mils. The product engineer wishes to increase the mean speed of the film, and believes that this can be achieved by reducing the thickness of the film to 20 mils. Eight samples of each film thickness are manufactured in a pilot production process, and the film speed (in microjoules per square inch) is measured. For the 25-mil film, the sample data result is = 1.15 and 81 = 0.11, while for the 20-mil film, the data yield 2 = 1.06 and 82 = 0.09. Note that an increase in film speed vould lower the value of the observation in microjoules per square inch. (a) Do the data support the claim that reducing the film thickness increases the mean speed of the film? Use a = 0.10 and assume that the two population variances are equal and the underlying population of film speed is normally distributed. What is the P-value for this test? Round your answer to three decimal places (e.g. 98.765). The data the claim that reducing the film…

According to the National Health and Nutrition Examination Survey (NHANES) sponsored by the U.S. government, a random sample of 712 males between 20 and 29 years of age and a random sample of 1,001 males over the age of 75 were chosen and the weight of each of the males were recorded (in kg). Do the data provide evidence that the younger male population weighs more (on average) than the older male population? Use “Y” for ages 20-29 and “S” for ages 75+. It was found that x̅Y=83.4, sY=18.7, x̅S=78.5, and sS=19.0. a) Is the normality condition met for this test? (see picture) No, since the histograms show skewness and outliers . Yes, since both sample sizes are larger than 30. No, since both sample sizes, nY and nS, are less than 30. Yes, since it was stated that the two populations are normally distributed. b)What are the correct degrees of freedom for this test? Group of answer choices 999 1000 1712 1711 711
