In a lot of 200 electrical fuses, 20 are known to be nonconforming. A sample of 10 fuses is selected. (a) What is the probability distribution of the number of nonconforming fuses in the sample? What are its mean and standard deviation? (b) Using the bino
In a lot of 200 electrical fuses, 20 are known to be nonconforming. A sample of 10 fuses is selected.(a) What is the probability distribution of the number of nonconforming fuses in the sample? What are its mean and standard deviation?(b) Using the binomial distribution as an approximation to the hypergeometric, find the probability of getting 2 nonconforming fuses. What is the probability of getting at most 2 nonconforming fuses?

Pleas TYPE your answers to the following questions. Thank you! A random set of 24 products is sampled from a production process. The fraction of non-conforming products manufactured by the process is thought to be 0:1, and each product is independently defective of the others. (a) What is the probability of 0 nonconforming products in the sample? 6 nonconforming products? 12 nonconforming products? 24 nonconforming products? (b) What is the probability that at most 4 products won't conform to specifications?...

5. (20 pts) Suppose on a given college campus 45% of the students own an iPhone, 50% an Android smartphone and 5% some other type of phone. Let X=the number of students in a simple random sample of 15 students who own an iPhone. A. What is the probability distribution of X? Note: If this is a well-known distribution it is sufficient to name the distribution and identify the value of the parameters B. Find the probability that 8 students...
