In a simple experiment, you are going out there to the duck pond to seine out one redbreast sunfish at random, determine its sex, and put it back in the pond and then, after 30 minutes, repeat this process. Assuming that the sex ratio for redbreast in the pond is 1:1, develop and plot the pmf of the random variable X, defined as the number of females in the two fish observed.
1. Is the distribution of X symmetric or asymmetric?
2. Explain why the result in (a) was obtained.
3. Describe a simple experiment (at most 2-3 sentences) that you would perform to determine whether the sex ratio is really 1:1.

Expert Solution

if the calculated value of T is between c1 and c2 then we can conclude that the sex ratio is 1:1. Otherwise not so.

Researchers used a standard fish seine to sample the fish population of Mason Pond. Most of these fish were bluegill (Lepomis macrochirus). Researchers removed fish from the seine and measured these fish on a fish board the boat. Researchers measured each fish to the nearest millimeter. Then, researchers measured all of the fish brought in by your seine, except for fish less than 15 mm. Size Category Observed Expected 15-35 mm 22 7.33 >35-55 mm 16 5.33 >55 mm...

Use Java Sample values from an experiment often need to be smoothed out. One simple approach is to replace each value in an array with the average of the value and its two neighboring values (or one neighboring value if it is at either end of the array). Given a class Data with instance fields private double[] values; private double valuesSize; implement a method public void smooth() that carries out this operation. You should not create another array in your...

Cobalt has spilled into a pond and our task is to precipitate it out. Your task is to choose a precipitation agent. It has been found that the cobalt is in the +2 state. After consulting your handy textbook, you see that the possible precipitants are carbonate, sulfide and hydroxide ions. Remember that the pH of the pond is already set. Based on what you know about equilibria, write the pertinent chemical reactions that would occur for each of the...

What to do This assignment is going to be pretty simple - we're just going compute frequency counts of certain colors in certain ranges (Histogram of the image). Because there is no natural way of segregating RGB color ranges, we usually do this color by color. So you'll be computing frequency counts for individual color components individually. The expectation is that you will write a function as described by a python function signature below (while you are free to do...

You are going to carry out a gastric lavage (stomach pump) in order to try and get rid of the aspirin that has not yet been absorbed. The procedure involves washing the organ with a solution of a certain pH containing activated charcoal to bind the aspirin. The pH of the stomach is typically around 2.0. Which of the following do you think would be the most effective lavage? Hint: think about the pH at which aspirin would cross the...

(Python language) Going out with the gang? You are planning an outing with some friends and need to calculate the total price of the tickets. A regular ticket usuallycosts$3.99 and a student ticket costs only $2.99. If the total number of tickets being ordered (including both students andregular tickets) is at least 10, then a 10% discount is applied to the order. However, if it is a holiday, then the at-least-tengroup discount is only 5% (not 10%).Write a functiontotalticketprice: given...

Before you write your paper, conduct this simple experiment on classical conditioning. You will need a bell (a set of keys works too, a hand-held mirror, and a room that becomes completely dark when the light is turned off. Hold the bell while standing in the room near the light switch. Once in position, ring the bell and then immediately turn off the light. Wait in total darkness for 15 seconds, then turn the light on. Wait another 15 seconds...
