In a scientific study that tries to relate the biodiversity of macro invertebrates to the acidity of the water near mines, samples of macro invertebrates were taken at the rate of a monthly sample for 12 months in two different locations. For the first locality, an average biodiversity index of 3.11 and a sample standard deviation of 0.771 were obtained. For the second locality the average biodiversity index was 2.04 with a standard deviation of 0.448. to. BUILD and INTERPRET a 90% confidence interval for the difference in the means of the two localities assuming that the populations conform approximately to a normal population and that the variances can be considered equal. (10 pts)

b. Assess whether the evidence supports the presumption of equal variances (5 pts)

c. Would it have been better to use a 95% range? Explain in detail (5 pts)

Three dimensions. Three point particles are fixed in place in an xyz coordinate system. Particle A, at the origin, has mass mA. Particle B, at xyz coordinates (3.00d, 2.00d, 4.00d), has mass 3.00mA, and particle C, at coordinates (–3.00d, 3.00d, –2.00d), has mass 3.00mA. A fourth particle D, with mass 3.00mA, is to be placed near the other particles. If distance d = 9.90 m, at what (a) x, (b) y, and (c) z coordinate should D be placed so that the net gravitational force on A from B, C, and D is zero?

I need the answer in meters. Also, I already asked and someone ended up getting 0 for part a, -16.5 for part b and 22.9 for part c; none of those are correct. thanks

Discuss whether the following items would meet the definition of an asset using the IFRS definitions. If so, explain with reference to the appropriate criteria. 1.A franchisee has a licence to operate a Tim Hortons restaurant. 2.The parent company has guaranteed the operating line of credit of its subsidiary, which resulted in the subsidiary obtaining a lower interest rate than it would otherwise receive. Is the guarantee an asset for the subsidiary? 3.FreshWater Inc. bottles and sells the spring water from a natural spring near its property. Is the natural spring an asset of the company? 4.Mountain Ski Resort Ltd. often has to use its snow-making machine to make snow for its hills and trails when there is not enough natural snowfall. Is the snow an asset for Mountain Ski?

From Case Project 10-5: Internet of Things in your textbook: Use the Internet to research the Internet of Things (IoT). You can find the case project by opening up your full book by clicking on the book icon in the right navigation bar from within Mindtap. You will then need to select Chapter 10, and page forward until you get to the case project section. In your own words, what is IoT? How is it being used today? How will it be used in the near future? What impact will IoT have on technology, society, and the economy over the next five years? What are its advantages and disadvantages? Finally, visit the IoT List site (iotlist.co) and identify five of the most unusual IoT devices. Write a one-page paper on the information that you find

The two wires carry current i1 and i2, respectively, with positive current to the right. The charge q is positive and has velocity v to the right.

True False  If i1 is greater than i2, then the force on q is north.
True False  If v = 0, then the force on q is zero.
True False  If i2 = - i1 then the force on q equals zero.
True False  If i2 = 0 and i1 is greater than zero, then the force on q points into the page.
True False  If i1 = 0 and i2 is greater than zero then the force on q is south.
True False  If i2 = 0 and i1 is greater than zero, then the magnetic field near charge q points out of the page.
True False  If i1 = i2, then the wires are attracted to each other.
