Does anyone use ratios in their workplace? If so, can you provide an example and explain how it is used.

Explain in words and in percentages what it would mean if you found that for variables x and y, the coefficient of determination r squared = 0.832

The ratio comparing the length from a person's elbow to their wrist and the length from their wrist to their fingertip is approximately equal to the golden ratio. O True O False MacBook Air 80 889 DII DD F3 F4 FS F6 F7 F8 F9 F10

For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding.In a combined study of northern pike, cutthroat trout, rainbow trout, and lake trout, it was found that 20out of 860fish died when caught and released using barbless hooks on flies or lures. All hooks were removed from the fish.   (a) Let prepresent the proportion of all pike and trout that die (i.e., pis the mortality rate) when caught and released using barbless hooks. Find a point estimate for p. (Round your answer to four decimal places.)(b) Find a 99% confidence interval for p. (Round your answers to three decimal places.) lower limit       upper limit

Can someone explain the formulas needed and what variables go where?   445 randomly selected bulbs were tested in a laboratory, 316 lasted more than 500 hours. Find a point estimate of the proportion of all bulbs that last more than 500 hours.

Español Weber's law, a concept taught in most Introduction to Psychology courses, states that the ratio of the intensity of a stimulus to the "just noticeable" increment in intensity is constant, that is, the ratio doesn't depend on the intensity of the stimulus. The ratio is called the "Weber fraction," so a concise statement of Weber's law is that "the Weber fraction is constant, regardless of the stimulus intensity." It turns out that Weber's law is not so much a law as it is a rule of thumb, since it is violated in many situations. For instance, for some auditory stimuli, the Weber fraction does depend systematically on the stimulus intensity. The following bivariate data are the experimental data obtained for one listener in an auditory intensity discrimination task. For each of the ten stimulus intensities x (in decibels), the Weber fraction y (in decibels) is shown. Figure 1 is a scatter plot of the data. Also given is the product of the stimulus intensity and the Weber fraction…
