Question:

The information in Figure 5.6, Table 5.18, and Table 5.19 resulted from bootstrapping the sample standard deviation for the variable BMI computed on the Body Fat data set. Use the information in Figure 5.6, Table 5.18, and Table 5.19 to answer the following:

(a) What is the bootstrap standard error of the sample standard deviation on BMI on the Body Fat data set?

(b) Does the bootstrap sampling distribution of the sample standard deviation appear to be normally distributed? Why?

(c) What is the interquartile range of the bootstrap sampling distribution of the sample standard deviation?

I believe that learning is a continuous process. I have been exposed to research after being enrolled to Indian Institute of Science Education and Research (IISER) Pune, a premier science institute in India. IISER Pune plays an important role in pursuing my degree in the field of scientific research. I did my master project in exploring the properties of nanomaterial and its various characteristics. This project had given me an opportunity to work together in a team and explore various experimental techniques relevant to my project. Personally, I want to see this world through the glasses of science. I always wonder why people hate science and love science fiction. This is not their mistake, may be it is not delivered properly. I had seen myself learning things which I don't like just because of good teachers. So what matters is a good teacher who could deliver the subject well enough to clear the concept of students. So in this field of learning, I what to learn science through making videos. Any video has a finalized product that tells a story. And this story is missing in all boring science lectures. This is why, I want to build stories of science which could connect to people and their lives. And in this way, I could use my researching skills as well. Talking about my tutoring experience, I have not much experience in teaching. But I know my subject well enough to teach somebody. I would say I love solving problems related to physics. And I build this habit of solving problem since when I started preparing for competitive exams
