Question:
The principle of unbiased estimation has been criticized on the grounds that in some situations the of fruit has a Poisson distribution with parameter μ. You are going to purchase two such pieces of fruit and wish to estimate
Transcribed Image Text:
0=e-2", the probability that neither of these has any blemishes. But your estimate is based on observing the value of X for a single piece. Obtain an estimator 0 = d(X) that is unbiased for 0; i.e., such that E[d(X)]=e-2". Set the summation for E[d(X)] equal to e-2", cancel e¯" from both sides, then expand what remains on the right-hand side in a Taylor series and compare the two sides to determine d(X). If X = 200, what is the estimate? Does this seem reasonable? What is the estimate if X 199? Is this reasonable? =

Before working at Mariakani, I volunteered at a local community center, where I tutored students from diverse backgrounds. I helped them improve their academic performance and develop self-esteem and confidence. I used creative teaching methods, such as role-playing and group discussions, to make the learning experience more engaging and enjoyable.
In addition, I have conducted workshops and training sessions for educators and mental health professionals on various topics related to counseling and psychology. I have presented research papers at conferences and published articles in academic journals.
Overall, I am passionate about sharing my knowledge and helping others achieve their goals. I believe that tutoring is an excellent way to make a positive impact on people's lives, and I am committed to providing high-quality, personalized instruction to my students.
