The text provides data and analysis parameters related to the speeds of randomly selected cars on a section of Highway 405 in Los Angeles, with a posted speed limit of 65 mph. Traffic engineers often use the "85th percentile rule" to set speed limits.### Data:- **Speeds (in mph):** - Row 1: 66, 68, 72, 73, 65, 75, 73, 72, 68, 65 - Row 2: 58, 66, 70, 71, 66, 74, 60, 71, 63, 72 - Row 3: 59, 75, 70, 56, 66, 75, 68, 75, 62, 72 - Row 4: 60, 73, 61, 75, 58, 74, 60### Frequency Analysis:- **Frequency Table:** - Class width: 3 - Midpoint of first class: 56### Statistical Analysis:- **Statistics:** - Mean - Standard Deviation (Std. Dev.) - Skewness (Skew) - Z-score- **5-number Summary:** - Minimum (MIN) - First Quartile (Q₁) - Median (Q₂) - Third Quartile (Q₃) - Maximum (MAX)### Visual Analysis:- **Ogive:** - Used for displaying cumulative frequencies graphically. - **Modified Box Plot:** - Useful for visualizing the spread of the speed data and identifying outliers.No specific labels, statistics, or data entries for the statistical analysis are provided in the text.

Given that midpoint of first class is 56 and class width is 3. Arrange the data in ascending order…

Listed below are recorded speeds (in miles/hour: mph) of randomly selected cars traveling on a section of Highwa 405 in Los Angeles (based upon data from Sigalert). That section has a posted speed limit of 65mph. Traffic engineers often establish speed limits by using the "85th percentile rule," whereby the speed limit is set so that 85% of drivers are at or below the speed limit. • Frequency Table: class width 3; midpoint of first class 56 68 68 72 73 65 75 73 72 68 65 65 73 66 71 68 74 66 71 65 73 59 75 72 66 58 70 56 75 68 75 62 60 73 61 75 74 60 73 58 75

Recall that a relative frequency histogram is used to graph quantitative data. Classes are chosen to divide the range of values into equal-length subintervals, then plotted along the horizontal axis. A bar is drawn for each class with height equal to the relative frequency for that class. To create a relative frequency histogram, first summarize the following data in a frequency table. 1 N 2 3 4 5 6 7 Class Class Boundaries 8 9 1.3 10 11 14.7 9.0 16.7 4.1 14.9 4.4 2.7 32.3 10.9 9.0 9.0 1.6 18.4 1.0 2.4 2.4 18.0 Since the measurements are all between the values 0 and 33, it will be convenient to choose 11 class intervals of length 3. Using the given data, tally the values within each class interval to determine the frequency of each class, and fill in the following table. 0 to <3 3.5 11.2 18.0 26.7 3.7 3 to 6 6 to 9 9 to 12 12 to < 15 15 to 18 18 to 21 21 to 24 24 to 27 0.2 6.1 13.5 27 to < 30 30 to 33 7.4 8.2 19.2 1 1 2 1 Frequency 10 5 1 4 1 X X 9.4 X 8.7 X 2.0 6.6 3.9 5.9 4.3 3.3 0.2…

Reyesburg Corporation is contemplating using a new, more expensive glue in the construction of its laminated veneer lumber. Of importance to the company is the carrying load of the lumber. The company has tested 32 beams using the new glue, recording for each beam the pressure (in pounds per square foot) at which the beam breaks. The data collected are presented in the following frequency distribution. Carrying load (in pounds per square foot) Frequency 860 to 879 4 880 to 899 9 900 to 919 12 920 to 939 4 940 to 959 3 Based on the frequency distribution, using the midpoint of each data class, estimate the mean carrying load of the beams tested. For your intermediate computations, use four or more decimal places, and round your answer to one decimal place. pounds per square foot ?
