An experiment to compare the spreading rates of five different brands of yellow interior latex paint available in a particular area used 4 gallons \((J = 4)\) of each paint. The sample average spreading rates \((ft^2/gal)\) for the five brands were: - \(\bar{x}_1 = 462.0\), - \(\bar{x}_2 = 512.8\), - \(\bar{x}_3 = 427.5\), - \(\bar{x}_4 = 469.3\), and - \(\bar{x}_5 = 532.1\).The computed value of \(F\) was found to be significant at a level \(\alpha = 0.05\). With \(MSE = 320.8\), use Tukey's procedure to investigate significant differences between brands. (Round your answer to two decimal places.)**Which means differ significantly from one another?

The average height X and weight Y of males in population have a bivariate normal distribution with means µX 1.80 m., µy 90.0 kgs and standard deviations Ox = 0.30 m., oy = 15.3 kgs respectively. The correlation coefficient between X and Y is p= 0.80.
Total fat content (including saturated fat and trans fats) is a key characteristic of cheese. Assume that for a given type of cheese, total fat content (10-1 g/g of cheese) follows a normal distribution with a population mean of 2.85 (unit) and a population variance of 0.01 (unit2). Such an assumption is reasonable because fat content varies inside cheese and the “errors” around the mean total fat content (i.e. the value appearing on the etiquette) are distributed like a bell shape. a) What is the probability that the total fat content of this cheese exceeds 3 (unit)? b) What is the probability that the total fat content varies from 2.8 to 3 (unit)?

A traffic office in a country was in charge of a study where the safety of passengers in different types of cars was examined. Three models were examined; small cars, minivans and SUVS and six cars in each category were inspected. A special traffic accident simulator was used in the study and the pressure on the drivers' heads was measured. Umferðarastofa wanted to investigate whether there was a difference in the average pressure on the head during a collision in these three types of cars and used a variance analysis for this purpose.
