Assume that a procedure yields a binomial distribution with n=5 trials and a probability of success of p=0.80. Use a binomial probability table to find the probability that the number of successes x is exactly 4.

In a sample of 225 people, would it be unusual to find that 40 people in the sample are left- (Click to view hint) handed? Find the approximate probability of at least 30 in 225 of being left-handed. What is the sample proportion? p = (Round to the nearest hundredth.) (Click to view hint) Write the problem using probability notation. P(p + 0.13) What is the Z-score? P(p ≥ 0.13) = P(z > to view hint) Which illustration (below) shows the area represented by this probability? ) (Click <

A textile manufacturing process finds that on average, three flaws occur per every 50 yards of material produced. What is the probability that exactly 2 flaws occur in a 50 yard piece of material? Round your answer to three decimal places with a zero to the left of the decimal. E.g., 12% would be 0.120, and 0.15551 would be 0.156.

Assume that a procedure yields a binomial distribution with n = 4 trials and a probability of success of p = 0.10. Use a binomial probability table to find the probability that the number of successes x is exactly 2. Click on the icon to view the binomial probabilities table.
