A company that manufactures rivets believes the shear strength (in pounds) is modeled by N(750,30). Use the 68–95–99.7 Rule to complete parts a) through c) below. a) Draw and label the Normal model. b) Would it be safe to use these rivets in a situation requiring a shear strength of 720 pounds? Explain. Choose the correct answer below. A. No, because about 32% of all of this company's rivets have a shear strength of less than 720 pounds. B. Yes, because very nearly all of this company's rivets have a shear strength of more than 720 pounds. C. No, because about 16% of all of this company's rivets have a shear strength of less than 720 pounds. D. Yes, because only about 2.5% of all of this company's rivets have a shear strength of less than 720 pounds. c) About what percent of these rivets can be expected to fall below 810 pounds?

Suppose that a company must service customers lying in an area of A square miles with n warehouses. Kolesar and Blum showed that when the warehouse(s) are located properly, the average distance between a warehouse and a customer is (????)12. Assume that it costs the company $90,000 per year to maintain a warehouse and $5,000,000 to build a warehouse. Also, assume that this $5,000,000 building cost is equivalent to incurring a cost of $500,000 per year indefinitely. The company fills 180,000 orders per year, and the shipping cost per order is $1.25 per mile. If the company serves an area of 120 square miles, how many warehouses (make it as an integer variable) should it have?

Silver Valley Club decided to install a fiber-optic cable system in its village. The table below has information on the distances between the various buildings in the village. Answer these questions: 1) How should the buildings be connected to minimize the total length of the cable? 2) Determine the length of cable required for the connection.
a. Suppose we had a triangular prism that was 14 cm long with atriangular base of 1 cm and a height of 0.8 cm. Whatwould the volume of that prism be, and do youbelieve that it actually is a better estimate? b. Suppose that we had a marker that was twice as thick and twice as tall, but the same length. Approximately how many of the cubes would we need to make a good estimate of its volume? Explain/show how you know this.
The edge x of a cube is measured with an error of at most 0.5%. What is the maximum corresponding percentage error in computing the cube’s a. surface area? b. volume?
A survey of 700 non fatal accidents showed that 287 involved defective equipment. Find a point estimate for p, the population proportion of accidents that involved defective equipment and round to 4 decimal places if needed.
(b) The estimated stress level for working at ABC was obtained from a few, not many, reviews on the Internet, so the estimate is rough. If the true stress level is believed to be in the range of 1 to 1.5 and its exact value cannot be known, explain whether Mary is able to determine the best time allocation. Please limit the answer to within one page.
A study wants to look at what % of the population is tall. If they want to estimate the percentage based on survey results, how many people must they survey to be 90% confident that they are within 6% of the population proportion? Assume that there's no preliminary data to work with. Show work please.
A recent survey in the United States reported the prevalence of a sexually transmitted disease called chlamydia among 14 to 39 is 1.7% (95% CI = 1.4% – 2.0%). What is the margin of error associated with this survey’s estimate of the prevalence of chlamydia? Suppose the prevalence of chlamydia among 14 to 39 in Great Britain is 1%. Do you think that the United States and Great Britain have the same true population prevalence of chlamydia among 14-39 year olds, why?
