The question of whether an optimal body size exists for different kinds of animals is one that is of great interest to biologists. The reproductive power P of an individual can be modeled, following the ideas of ecologist James H. Brown (see his book Macroecology, University of Chicago Press, 1995), as the harmonic mean of two limiting rates. The harmonic mean of two numbers a and b is the reciprocals of the average of the inverses of the two numbers: ab a+b a The two rates are a per-unit-mass rate R1 at which individuals acquire resources, and a per-unit-mass rate R, at which individuals convert those resources into new individuals; that is, P = R¡R2 R1+R2 Assuming both Rị and R2 are the following allometric functions of body mass measure in kilograms R1 = 2M³/4 and R2 = 4M¯1/4, find the body mass M that maximizes the reproductive power P, M = kg.
Question 3 A survey sponsored by The American Dietetic Association and the agribusiness giant ConAgra found that 53% of office workers take 30 minutes or less for lunch each day. Approximately 37% take 30 to 60 minutes, and 10% take more than an hour. What additional information you want to know before you accepted the results of the survey? 2. Discuss the four types of survey errors in the context of this survey
Decide if each of the following problems is a linearization problem, an optimization prob- lem, a related rates problem, a graphing problem, or a Newton's method problem. Identify. Label the problem as one of the five types or explain that it is not exactly one of those types (and how you know). Begin solution. For each problem, start the solution.
Could you answer these three as well? My apologies for not clarifiying these are the ones I really need help with. I do provide positive feedback and votes for who answers. Thank you! How sensitive are our consumers to changes in the rival good’s price? Explain in detail. Suppose we decide to charge a per ounce price of $2, while at the same time our rival charges a price of $2.15. All else equal, what would you expect sales to be? How confident are you in your forecast? Suppose we are charging a price of $2 and our current marginal cost is $1.50 Are we maximizing profits at this price? If not, should we raise or lower price? Why?

Dispersion. I need an explanation on how to do these kinds of problems.
I'm stuck, can someone explain how to solve? note: it would be appreciated if you double-check your work (I have had experts provide me with incorrect solutions before and it would confuse me). Thank you!
(Additional information for Questions 24 and 25). Theory of mind (ToM) is known as a social cognitive ability in which children are able to recognize that other's have different desires, beliefs, and emotions that are different from oneself. Child on the autism spectrum tend to acquire this ability later in development than typically developing children. The psychologists wanted to examine if children on different levels of the spectrum vary on whether they are able to pass or fail a theory of mind task. After testing the 100 children they sampled on a Theory of mind task, here's what they found using the three level of AS they identified in the previous section of this section: Pass ToM Fail ToM Low AS 20 24 Middle AS High AS 12 18 10 16

Problem 10.5. Are sexually active teenagers any better informed about AIDS and other potential health problems related to sex than teenagers who are sexually inactive? A 15-item test of general knowledge about sex and health was administered to random samples of teens who are sexually inactive, teens who are sexually active but with only a single partner, and teens who are sexually active with more than one partner. Is there any significant difference on the test scores? Use the graph below to find the answer.
The next three questions are based on the following information: We're trying to determine if Lamborghini Aventador and Ferrari Enzo are different from each other based on their speed. In order to test this we record the average speed of 50 laps for each car. Which of the following is our alternate hypothesis O A. H1: Population average speed (Lamborghini) - Population average speed (Ferrari) = 0 B. H1: Population average speed (Lamborghini) - Population average speed (Ferrari) not equal to 0 C. H1: Population average speed (Lamborghini) - Population average speed (Ferrari) > 0 D. H1: Population average speed (Lamborghini) - Population average speed (Ferrari) < 0
