A random sample of 83 reconstructed clay vessels from the Turquoise Ridge archaeological site indicated the standard deviation of diameters to be approximately 5.5 cm. How many more such clay vessels must be found and reconstructed to be 95% sure that the sample mean of diameters is within 1 cm of the population mean of all such reconstructed clay vessels at this archaeological site?

In most cases a validation of the estimate is a sanity check' to ensure that the estimate is reasonable. What strategies and processes are used to conduct a validation of an estimate? Provide a brief explanation of each. (50-80 words)

As the tempering temperature of a heat-treated steel increases, the associated values of Brinell hardness also increases, while the values of tensile strength and yield strength decrease. True False   The correct definition of Dimensional Analysis is:     A procedure to find the yield point of a material when no definitive yield point can be determined graphically.     A procedure to calculate the Elastic Modulus.     A procedure to verify the size of a mass of material.     A methodical process of converting from one set of units to another set of units.

What term describes a numerical value that can be applied to a dimensional constraint in a technical drawing that will restrict variation on a part feature yet keep part feature functionality? Please answer quickly

Part 1: Suppose that our company performs DNA analysis for a law enforcement agency. We currently have 1 machine that are essential to performing the analysis. When an analysis is performed, the machine is in use for half of the day. Thus, each machine of this type can perform at most two DNA analyses per day. Based on past experience, the distribution of analyses needing to be performed on any given day are as follows: (Fill in the table)   Part2: We are considering purchasing a second machine. For each analysis that the machine is in use, we profit 1400$. What is the YEARLY expected value of this new machine ( ASSUME 365 days per year - no weekends or holidays

Hello, so i have attached two images. the first image is the quetions, i need part b) answered if possible. i have attached my findings to part a) to add to the little information we know to help with part b if needed. Thnks

Question 2 In a test measuring the life span of a certain brand of tire, 100 tires are tested. The results showed an average lifetime of 50,000 miles, with a standard deviation of 5,000 miles. One hundred thousand of these tires have been sold and are on the road. (a) After what mileage would you expect 10% of the tires to have worn out? (b) How many tires are expected to wear out between 60,000 and 70,000 miles? (c) How many tires are expected to have a life of less than 20,000 miles? (d) What are your major assumptions in the calculations for (a), (b) and (c)? (e) Estimate the 95% confidence interval on the population mean.

Question 2 You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial weight bearing activities. Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the yield stress for the…

X Incorrect. A 40 wt% Ni-60 wt% Cu alloy (Animated Figure 9.3a) is slowly cooled from 1400°C (2550°F) to 1150°C (2100°F). (a) At what temperature does the first solid phase form? i 1320 °C (b) What is the composition of this solid phase? i 62 %wt Ni (c) At what temperature does the last of the liquid solidify? i 1270 °C (d) What is the composition of this last remaining liquid phase? i 38 %wt Ni

(c) How many significant figures are there in the value 0.00470 centimeters? (d) The mass of a rock sample is measured four times, yielding values of 24.996 grams, 25.008 grams, 25.011 grams, and 25.005 grams. What is the average mass of the sample in units of grams? The average value is determined by taking the sum of all samples and dividing by the total number of samples.
