- What is the purpose of the Intermediate Value Theorem?a.How many degrees of freedom are there? b.What is the critical F at the .10 level c.One of Mendel’s famous experiments with peas resulted in 580 offspring, and 152 of them were yellow peas. Mendel claimed that under the same conditions, 25% of offspring peas would be yellow. Assume that Mendel’s claim of 25% is true, and assume that a sample consists of 580 offspring peas. Use the range rule of thumb to identify the limits separating values that are significantly low and those that are significantly high. Based on the results, is the result of 152 yellow peas either significantly low or significantly high? Find the probability of exactly 152 yellow peas. Find the probability of 152 or more yellow peas. Which probability is relevant for determining whether 152 peas is significantly high: the probability from part (b) or part (c)? Based on the relevant probability, is the result of 152 yellow peas significantly high? What do the results suggest about Mendel’s claim of 25%?
- State TRUE or FALSE for the following statements. The mumber of fully vaccinated students in Emerald College is an example of a continuous variable. i. ii. A variable with ordinal level of measurement has all the characteristics of a variable with ratio level of measurement, and there exists a true zero. iii. Rating a hotel by the number of stars is an example of a nominal level of measurement. iv. Inferential statistics is the branch of statistics that involves generalizing from sample to population from which it was selected. v. Skewness values range from 0 to 1. vi. Stem and leaf display is an effective graphical technique for showing the qualitative data vii. The sample space of an experiment is the set of all possible outcomes of that experiment. viii. Classical probability approach uses a frequency distribution to compute probability.Note:;- Please need all the answers to the problem and need full expectations with methods.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.
- Imagine that a professor of psychology has two teaching assistants (TAs) who will help her grade assignments for the duration of the semester. The professor wants to make sure that she and the TAs are well calibrated with one another, so she has all three of them grade the first assignment independently. Because the professor grades every assignment on a curve, she first converts the students’ scores to z-scores for each grader. The following table shows the z-scores for a population of 10 students in her class for each grader. Professor Teaching Assistant #1 Teaching Assistant #2 Student 1 0.70 1.27 1.27 Student 2 0.83 -0.64 -1.55 Student 3 -0.98 0.38 -0.14 Student 4 2.21 0.80 0.92 Student 5 -0.54 -1.34 -1.06 Student 6 0.43 0.10 0.30 Student 7 -1.03 -2.09 -1.50 Student 8 -0.01 0.85 1.14 Student 9 -0.54 0.48 0.57 Student 10 -1.07 0.20 0.04 The professor is going to use the z-scores to calculate the correlation coefficient between her scores…Could someone please help explain this to me? I have gotten the question wrong twice now. I reviewed the Central Limit Theroem and thought I was on the right track for the question but it appears I don't understand.From the following data of the daily wage of 500 workers of a factory find the number of workers : (a) whose wages are more than $ 370 but not more than $ 400. (b) whose wages are less than $ 370 but not less than $ 350. Wages not exceeding $ 300 =150 workers Wages not exceeding $ 350 = 180 workers Wages not exxceeding $ 400 = 240 workers Wages not exceeding $ 450 = 400 workers Wages not exceeding $ 500 = 500 workers
