The first questions asks how do I describe the distribution. I wanted to say right skewed but there are data concentrated on the right most side. So, is this a bimodal distribution? Also, is it save to conclude that the birds generalize in both strategies? Researchers studied the food-obtaining behavior of the bird known as *Parus major*. In the wild, the birds can obtain food by finding it themselves or by taking advantage of the efforts of other birds via scrounging (e.g., stealing the food of others, joining food patches found by others). To investigate this behavior, researchers set up a puzzle-box where the bird slides a door to the side to reveal food, and the door stays open long enough for a non-solving bird to also take some of the food.The researchers used radio-frequency identification (RFID) tags to individually track data for each bird. They also used cameras to distinguish when a bird employed the producing strategy of solving the puzzle from when a bird scrounged by taking food after a different bird solved the puzzle. The researchers examined if the birds tended to generalize across the producing and scrounging strategies, if they specialized in a strategy, or if they showed some other pattern of food-obtaining behavior.The histogram shows the proportion of each bird's total visits to the puzzle box that were scrounges. The frequencies indicate the number of birds whose visits to the box have the specified proportion of scrounges. Only birds with at least 50 visits are included.### Histogram Explanation:- **X-Axis (Proportion of Scrounges):** This axis represents the proportion of total visits that were scrounges, ranging from 0 to 1.0.- **Y-Axis (Frequency):** This axis shows the frequency, or the number of birds, that display each proportion of scrounging.- **Distribution:** The histogram reveals a bimodal distribution with peaks around the 0.1-0.3 and near 1.0 proportions, indicating two prevalent scrounging behaviors among the birds. Some birds scrounged infrequently, while others did so almost exclusively.This data helps understand the variation in foraging strategies among the bird population studied.

Question

The first questions asks how do I describe the distribution. I wanted to say right skewed but there are data concentrated on the right most side. So, is this a bimodal distribution?

Also, is it save to conclude that the birds generalize in both strategies?

Researchers studied the food-obtaining behavior of the bird known as *Parus major*. In the wild, the birds can obtain food by finding it themselves or by taking advantage of the efforts of other birds via scrounging (e.g., stealing the food of others, joining food patches found by others). To investigate this behavior, researchers set up a puzzle-box where the bird slides a door to the side to reveal food, and the door stays open long enough for a non-solving bird to also take some of the food.

The researchers used radio-frequency identification (RFID) tags to individually track data for each bird. They also used cameras to distinguish when a bird employed the producing strategy of solving the puzzle from when a bird scrounged by taking food after a different bird solved the puzzle. The researchers examined if the birds tended to generalize across the producing and scrounging strategies, if they specialized in a strategy, or if they showed some other pattern of food-obtaining behavior.

The histogram shows the proportion of each bird's total visits to the puzzle box that were scrounges. The frequencies indicate the number of birds whose visits to the box have the specified proportion of scrounges. Only birds with at least 50 visits are included.

### Histogram Explanation:

- **X-Axis (Proportion of Scrounges):** This axis represents the proportion of total visits that were scrounges, ranging from 0 to 1.0.
- **Y-Axis (Frequency):** This axis shows the frequency, or the number of birds, that display each proportion of scrounging.
- **Distribution:** The histogram reveals a bimodal distribution with peaks around the 0.1-0.3 and near 1.0 proportions, indicating two prevalent scrounging behaviors among the birds. Some birds scrounged infrequently, while others did so almost exclusively.

This data helps understand the variation in foraging strategies among the bird population studied.

Here is an example from John and Jenn. When we return exams in our classes, we find it beneficial to share with students information on the distribution of scores. We provide this information so that students will have an idea of how they scored on the exam in comparison to their peers. However, deciding which descriptive information to provide to the class is not always an easy decision. These are modified grades from one of Jenn’s statistics classes. For this data set, the mean is 77, the mode is 92, and the median is 86. If you were the professor of the class, do you think sharing the mean scores on the exam with the class is a representative score of the data set? Why or why not? 9 or 11.

EXAMPLE 4.9 Students who seek therapy at university counseling centers often do not attend many sessions. For example, in one study, the median number of therapy sessions was 3 and the mean was 4.6 (Hatchett, 2003). Let’s examine the spread of fictional scores for a sample of five students: 1, 2, 4, 4, and 10 therapy sessions, with a mean of 4.2. We find out how far each score deviates from the mean by subtracting the mean from every score. First, we label with an X the column that lists the scores. Here, the second column includes the results we get when we subtract the mean from each score, or X − M. We call each of these a deviation from the mean (or just a deviation)—the amount that a score in a sample differs from the mean of the sample. X X − M 1 − 3.2 2 − 2.2 4 − 0.2 4 − 0.2 10 5.8 But we can’t just take the mean of the deviations. If we do (and if you try this, don’t forget the signs—negative and positive), we get 0—every time. Are you surprised?…
Use the following scenario to answer the next 6 questions: M&Ms are your favorite vending machine snack and you purchase them often. Lately, it seems like the bags have been having a disproportionate distribution of the colors. The company claims that 24% of the candies per bag should be blue. You decide to test this claim for yourself. You purchase a large bag and find that 38 of the 224 candies are blue. Before complaining to the company, you want to be fairly sure of your accusation, so you set a 1% significance level for your test. Do you have sufficient evidence that the color distribution is different than advertised? Based on the data, the value of the test statistic is:
