### Sampling Distribution ComparisonOlivia, Nicholas, Chloe, and Ethan each took many samples from the same population of students. The number of students in each of their samples is shown in the table below. Which person's sampling distribution is most likely to closely approximate the population distribution?| **Person taking sample** | **Number of students in each sample** ||----------------------------|--------------------------------------|| Olivia | 29 || Nicholas | 91 || Chloe | 56 || Ethan | 70 |In this example, each individual (Olivia, Nicholas, Chloe, and Ethan) collected different-sized samples from a student population. To determine whose sampling distribution most closely approximates the population distribution, it's essential to consider the number of students in each sample. Generally, larger samples tend to provide better approximations of the population distribution due to their higher likelihood of capturing the population's characteristics.- **Olivia** collected a sample of 29 students.- **Nicholas** collected a sample of 91 students.- **Chloe** collected a sample of 56 students.- **Ethan** collected a sample of 70 students.Based on the number of students in each sample, **Nicholas**, with the largest sample size of 91 students, is most likely to have a sampling distribution that closely approximates the population distribution. ### Multiple Choice Question:Please select your answer from the options below:- **A. Olivia**- **B. Nicholas**- **C. Ethan**- **D. Chloe**(Note: This image appears to be part of an online quiz or survey where participants are required to choose one of the options provided.)

A biologist is studying the composition of birds on a lake and counts 61 ducks, 17 geese, 11 cranes, 15 swans, and 6 herons. From previous studies performed around the same time of the year, she expects 50% of the birds to be ducks, 23% to be geese, 12% to be cranes, 10% to be swans, and 5% to be herons.

People often match their behavior to their social environment. One study of this idea first established that the type of music most preferred by black college students is R&B and that white college students' most preferred music is rock. Will students hosting a small group of other students choose music that matches the makeup of the people attending? Assign 9090 black business students at random to three equal‑sized groups. Do the same for 9696 white students. Each student sees a picture of the people he or she will host. Group 1 sees six blacks, Group 2 sees three whites and three blacks, and Group 3 sees six whites. Ask how likely the host is to play the type of music preferred by the other race. Use ANOVA to compare the three groups to see whether the racial mix of the gathering affects the choice of music.
A statistics teacher asked two different students, Lexie and Jennifer, to go to Wegmans and sample 30 shoppers each. The population of interest for both people can be defined as, “People who shop at the Johnson City, NY Wegmans store”. Here is what each person did to collect their sample: Lexie: She stood outside at the entrance to the store on 3 different days and times and surveyed every 15th person to walk by her. She surveyed 10 people each time to get her 30. Jennifer: She went to Wegmans after her nursing shift first thing Wednesday morning to buy deodorant since she ran out. When she was in the pharmacy area she surveyed all the people around her and then, to get up to 30 surveys, she went to the health food section and surveyed everyone she was there. Identify at least 2 specific reasons why Lexie’s approach is more likely to give a representative sample. Consider sources of bias, or types of shoppers who might be excluded by Jennifer’s approach.…
