Engineers at a large company are trying to investigate if there is any difference in the average wear of brand A, brand B or brand C tires for the company's new models. To help them arrive at a decision, an experiment is conducted using 11 of each brand. The tires are run until they wear out. The results ( in kilometres) are as follows: Brand A: x = 37,900 Sį = 5100 Brand B: X2 = 39,800 S2 = 5900 Brand C: X3 =38,500 5600

Can balloons hold more air or more water before bursting? A student purchased a large bag of 12-inch balloons. He randomly selected 10 balloons from the bag and then randomly assigned half of them to be filled with air until bursting and the other half to be filled with water until bursting. He used devices to measure the amount of air and water was dispensed until the balloons burst. Here are the data
a.In an aquaculture study the following variables were measured on each fish: sex. Initial weight (g), bodytemperature (C), weight gain (g). For each variable indicate the scale of measurement. (b) A weed killer is to be applied at a rate of two ounces per 1000gallons of water (2oz/1000gallons). What is the application rate in ml/1000litrtrs if there are 28.375 ml/oz and 4.5liters/gallon? (c) The term test scores of 15 students enrolled in a Business statistics class were recorded inascending order as follows 4, 7, 7, 9, 10, 11, 13, 15, 15, 15, 17, 17, 19, 19, 20. After calculatingthe mean, median and the mode an error is discovered: one of the 15’s is really a 17. Of the threemeasures of central tendency which will change? (d) A student discovers that his grade on a recent test was the 72 nd percentile. If 90 students wrotethe test, then approximately how many students received a higher grade than he did?
The object of a general chemistry experiment is to determine the amount (in millilitres [mL]) of sodium hydroxide (NaOH) solution needed to neutralize 1 g of a specified acid. This will be an exact amount, but when the experiment is run in the laboratory, variation will occur as the result of experimental error. Three titrations are made using phenolphthalein as an indicator of the neutrality of the solution (pH equals 7 for a neutral solution). The three volumes of NaOH required to attain a pH of 7 in each of the three titrations are as follows: 82.20, 75.80, and 75.34 mL. Use a 99% confidence interval to estimate the mean number of millilitres required to neutralize 1 g of the acid. (Round your answers to three decimal places.) mL to

Wolf packs tend to be large extended family groups that have a well-defined hunting territory. Wolves not in the pack are driven out of the territory or killed. In ecologically similar regions, is the size of an extended wolf pack related to size of hunting region? Using radio collars on wolves, the size of the hunting region can be estimated for a given pack of wolves. Let x represent the number of wolves in an extended pack and y represent the size of the hunting region in km2/1000. The following data are representative of one of the national parks. x wolves 29 37 22 61 94 y km2/1000 7.35 12.18 8.15 15.39 16.81 (a) Verify that Σx = 243, Σy = 59.88, Σx2 = 15,251, Σy2 = 788.2256, Σxy = 3362.04, and r ≈ 0.9135.

A student is concerned with the amount of air pollution students are exposed to in the school's parking lot after school. The student conducts an investigation to compare the quantity of particulate matter released from the diesel-powered buses, natural gas-powered buses, and the large and small cars as they idle waiting to pick up students. To make measurements, a small piece of white fabric is used to collect particulate matter from the tailpipe of each vehicle as it idles for five minutes. Each piece of fabric is then analyzed to measure the amount of particulate matter it collected. (i) Identify the independent variable in the investigation. (j) Identify one variable that was not mentioned in the description that could affect the results of the investigation. (k) Describe a realistic alternate sampling method to collect particulate matter from the vehicles in the investigation. (1) The student wants to ensure that the results are reliable. Explain how the student could modify the…
