Find the probability of more than 30 heads in 50 flips of a fair coin by using the normal approximation to the binomial distribution. a) Check the possibility to meet the requirements to use normal approximation (show your calculation) b) Find the normal parameters of the mean(Mu) and standard deviation from the binomial distribution. c) Apply normal approximation by using P(X>30.5) with continuity correction and find the probability from the table of standard normal distribution.

2.A researcher believes that about 70% of the seeds planted with the aid of a new chemical fertilizer will germinate. He chooses a random sample of 140 seeds and plants them with the aid of the fertilizer. Assuming his belief to be true, approximate the probability that more than 97 of the 140 seeds will germinate. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round...

Ceramics in a factory are manufactured in lots of 200 and 3% are defective. Assume the pieces are independent. Use the normal approximation to the binomial with the continuity correction to find the probability more than 10 are defective. 0.031 (Correct) And, use the normal approximation to the binomial with the continuity correction to find the probability there are between 4 and 8 defects, inclusive. 0.5832 (incorrect) I try the second question but my answer is in correct.

Among students at a particular university, 90% have visited the main dining hall at least once. What is the probability that of 100 randomly selected students, between 90-93 of them will have visited the main dining hall at least once? Answer this question using the binomial distribution. Approximate this answer using the normal distribution without the continuity correction. Approximate this answer using the normal distribution and the continuity correction. (Take note of how close your approximation is.)

If 41 people are at a party, what is the probability that more than two of them have the same birthday? Assume that there are 365 days in a year and all days are equally likely to be the birthday of a specific person. Use Taylor series expansion of the exponential function to provide a first-order approximation of the result if necessary.
