A particular county employs three assessors whoare responsible for determining the value of residentialproperty in the county. To see whether these assessors differ systematically in their appraisals, 5 houses are selected, and each assessor is asked to determine the marketvalue of each house. Explain why a randomized block experiment (with blocks corresponding to the 5 houses) was used rather than a completely randomized experiment involving a total of 15 houses with each assessor asked to appraise 5 different houses (a different group of5 for each assessor)

A banana grower has three fertilizers from which to choose. He would like to determine which fertilizer produces banana trees with the largest yield (measured in pounds of bananas produced). The banana grower has noticed that there is a difference in the average yields of the banana trees depending on which side of the farm they are planted (South Side, North Side, West Side, or East Side), therefore, a randomized block design is used in the study. Because of the variation in yields among the areas on the farm, the farmer has decided to randomly select three trees within each area and then randomly assign the fertilizers to the trees. After harvesting the bananas, he calculates the yields of the trees within each of the areas. Can the banana grower conclude that there is a significant difference among the average yields of the banana trees for the three fertilizers? The results are as follows.  Average Yield of Banana Trees Side of Farm Fertilizer A Fertilizer B Fertilizer C…

Known for their grand design and impeccable aesthetic, UQ's lecture theatres are well appreciated by their students. In fact, some lecture theatres even have sound systems with high quality sound opposed to standard sound. However, the high quality sound systems face issues and sometimes do not work faultlessly. In fact, it is known that these high quality sound systems work faultlessly 86% of the time each week. A random sample of 10 lecture theatres with high quality sound is selected and monitored over the week. What is the probability that these lecture theatres work faultlessly more than seven times? (3 decimal places) Note:- Do not provide handwritten solution. Maintain accuracy and quality in your answer. Take care of plagiarism. Answer completely. You will get up vote for sure.

The following is a list of 14 measurements. - 13, -6, -45, 53, -3, 83, –23, 79, – 17, -96, – 18, 91, 53, – 13 Send data to calculator Send data to Excel Suppose that these 14 measurements are respectively labeled x,, x,, ..., x: (Thus, -13 is labeled x,, -6 is labeled x,, and so on.)
