Yolanda wishes to develop a new type of meatloaf to sell at her restaurant. She decides to combine 2 pounds of ground sirloin (cost $2.70 per pound). 1 pound of ground turkey (cost $1.30 per pound), and = pound of ground pork (cost $1.80 per pound). What is the cost per pound of the meatloaf?An engineer is studying bearing failures for two different materials in aircraft gas turbine engines. The following data are failure times (in millions of cycles) for samples of the two material types. Material A Material B 3.17 5.88 5.78 9.65 4.31 6.91 8.71 13.44 4.52 8.01 8.84 14.71 4.68 8.97 7.23 16.39 5.69 11 02 8.20 24.37 (a) Determine the sample mean failure time for each material (b) By hand, compute the median failure time for each material. (c) Determine the sample standard deviation of the failure times for each material. Which material has its failure times more dispersed? (d) By hand, compute the five-number summary for each material. (e) On the same graph, draw boxplots for the two materials. Annotate the graph with some general remarks comparing the failure times. (f ) Describe the shape of the distribution of each material using the boxplot and quartiles.The following data represent the weights (in grams) of 50 randomly selected quarters. Determine and interpret the quartiles. Does the data set contain any outliers? 5.49 5.58 5.60 5 62 5.68 5.52 5.58 560 563 5.70 5.53 5.58 5.60 5.63 5.71 5.53 5.58 5.60 5.63 5.71 5.53 5.58 5.60 5.65 5.72 5.58 5.58 5.60 5.68 5.73 5.57 5.59 5.60 5.68 5.73 5.57 5.59 5.61 568 5.73 5.57 5.59 5.62 567 5.74 5.57 5.59 5.62 2 5.67 5.84According to the National Center for Health Statistics, a 10-year-old male whose height is 53.5 inches has a height that is at the 15th percentile. Explain what this means.The distribution of income tends to be skewed to the right. Suppose you are running for a congressional seat and wish to portray that the average income in your district is low. Which measure of central tendency, the mean or the median, would you report? Why?Skinfold Thickness Procedure One method of estimating body fat is through skinfold thickness measurement. The measurement can use from three to nine different standard anatomical sites around the body. The right side is usually only measured (for consistency). The tester pinches the skin at the appropriate site to raise a double layer of skin and the underlying adipose tissue. but not the muscle. Calipers are then applied 1 centimeter below and at right angles to the pinch and a reading is taken 2 seconds later. The mean of two measurements should be taken. If the two measurements differ greatly, a third should be done and then the median value taken. Explain why a median is used as the measure of central tendency when three measures are taken, rather than the mean.Answer the following based on the histograms shown to the right. (a) Which measure of central tendency would you recommend reporting for the data whose histogram is shown in Figure I? Why? (b) Which one has more dispersion? Explain. 20 200 700 16 Frequency 480 520 IIThe median for the given set of six ordered data values is 28.5. What is the missing value? 7 12 21 41 50Miles per Gallon The following data represent the miles per gallon for a 2013 Ford Fusion for six randomly selected vehicles. Compute the mean, median, and mode miles per gallon. Source: www.fueleconomy.gov 34.0, 33.2. 37.0, 29.4, 23.8. 25.9\fConcrete Mix A certain type of concrete mix is designed to withstand 3000 pounds per square inch (psi) of pressure. The concrete is poured into casting cylinders and allowed to set for 28 days. The concrete's strength is then measured. The following data represent the strength of nine randomly selected casts (in psi). Compute the mean, median, and mode strength of the concrete [n psi)- 3980, 4090, 3200, 3100, 2040. 3830. 4080. 4040. 3780Flight Time The following data represent the flight time (in minutes) of a random sample of seven flights from Las Vegas, Nevada, to Newark, New Jersey, on Continental Airlines. 282, 270. 280, 286, 257, 260, 287 Compute the mean, median, and mode flight time.Match the histograms shown to the summary statistics: Mean | Median 42 42 31 38 III 31 31 32 Frequency (a) Frequency -10 10 30 30 70 20 (b) Frequency S L -7.5 7.5 225 37.3 523 675 (c) Frequency (d)Exam Scores The data in the next column represent exam scores in a statistics class taught using traditional lecture and a class taught using a "flipped" classroom. The "flipped" classroom is one where the content is delivered via video and watched at home. while class time is used for homework and activities. Traditional 70.8 69.1 79.4 67.6 853 78.2 56.2 813 80.9 715 637 698 59.8 Flipped 76.4 71.6 634 724 77.9 918 789 76.8 821 70.2 915 778 765 Source: Michael Sullivan (a) Determine the mean and median score for each class. Comment on any differences. (b) Suppose the score of 59.8 in the traditional course was incorrectly recorded as 598. How does this affect the mean? the median? What property does this illustrate
