A recent article in Business insider shows that 35% of the world wide smartphone markeyt is held by Apple. Suppose a randdom and independet sample of 240 people is selected.
a) If X is the number of people in the sample who own an Apple smartphone, can we assume a binomial distribution for X? Explain.
b) Use normal distribution (as an approximation to binomial) to calculate probability that less than 100 of them own an Apple smartphone.

A recent article in the paper claims that business ethics are at an all-time low. Reporting on a recent sample, the paper claims that 45% of all employees believe their company president possesses low ethical standards. Suppose 20 of a company's employees are randomly and independently sampled and asked if they believe their company president has low ethical standards and their years of experience at the company. Could the probability distribution for the number of years of experience be modeled by...

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...

Employee Satisfaction Rates: A recent poll suggests that 48% of Americans are satisfied with their job. You have a company with 226 employees and a poll suggests that 89 of them are satisfied (about 39%). (a) Assume the 48% general satisfaction rate is accurate. In all random samples of 226 Americans, what is the mean and standard deviation for the number of people satisfied with their job? Round both answers to 1 decimal place. \muμ = \sigmaσ = (b) Convert...

Uninsured Patients: It is estimated that 16.8% of all adults in the U.S. are uninsured. You take a random sample of 240 adults seen by a certain clinic and find that 47 (about 20% of them) are uninsured. (a) Assume the 16.8% value is accurate. In all random samples of 240 U.S. adults, what is the mean and standard deviation for the number of those who are uninsured? Round both answers to 1 decimal place. μ = σ = (b)...

2)According to a 2009 Reader's Digest article, people throw away about 12% of what they buy at the grocery store. Assume this is the true proportion and you plan to randomly survey 68 grocery shoppers to investigate their behavior. What is the probability that the sample proportion does not exceed 0.18? Note: You should keep at least 4 decimal places for any intermediate calculations you make to match wamap's approach and calculations. Answer = (Enter your answer as a number accurate...
