In the law firm Tybo and Associates, there are six partners. Listed is the number of cases each partner actually tried in court last month.| Partner | Number of Cases ||-----------|-----------------|| Ruud | 3 || Wu | 6 || Sass | 3 || Flores | 3 || Wilhelms | 0 || Schueller | 1 |**a.** How many different samples of 3 are possible without replacement?- **Box for input:** Number of possible samples**b & c.** Using samples of size 3 without replacement, compare the mean of the distribution of sample means to the population mean. *(Round your sample means and population mean answers to 2 decimal places.)* **Educational Website Content: Understanding Sample Means and Population Means**The images provided illustrate a table format commonly used in statistics to calculate sample means and compare them with population means. Let's break down the components:### Table 1: Sample Data Analysis**Columns:**1. **Sample**: This column lists various combinations of names, presumably representing different data points or groups within a study.2. **Sum**: A column for entering the total value obtained by adding the data points of each sample.3. **Mean**: A column for recording the average value of each sample, calculated by dividing the sum by the number of data points.**Sample Combinations:**- The table consists of combinations labeled with names like Ruud, Wu, Sass, Flores, Wilhelms, and Schueller. Each row represents a different sample.### Table 2: Distribution and Population Mean **Columns:**1. **Mean of the Distribution of the Sample Mean**: A space to calculate and record the average of all individual sample means.2. **Population Mean**: A space to record the actual mean of the entire population being studied.### Instructional Notes:- **Calculation of Sample Means**: To find the mean for each sample, sum the data points and divide by the number of points.- **Comparison with Population Mean**: After calculating the means of the samples, compare these to the population mean to analyze how well the samples represent the overall population.- **Statement Below the Table**: It prompts the user to provide a conclusion about the comparison between the mean of the distribution of sample means and the population mean.This exercise is crucial in understanding the law of large numbers and central limit theorem, which explain how sample means approximate the population mean as the number of samples increases.

Bill Alther is a zoologist who studies Anna's hummingbird (Calypte anna). (Reference: Hummingbirds, K. Long, W. Alther.) Suppose that in a remote part of the Grand Canyon, a random sample of six of these birds was caught, weighed, and released. The weights (in grams) were as follows. 3.7 2.9 3.8 4.2 4.8 3.1 The sample mean is = 3.75 grams. Let x be a random variable representing weights of hummingbirds in this part of the Grand Canyon. We assume that x has a normal distribution and ? = 0.64 gram. Suppose it is known that for the population of all Anna's hummingbirds, the mean weight is ? = 4.30 grams.
