Binomial Distribution. Research shows that in the U.S. federal courts, about 90% of defendants are found guilty in criminal trials. Suppose we take a random sample of 25 trials. (For this problem it is best to use the Binomial Tables). Based on a proportion of .90, what is the probability of less than 24 convictions?

A 2020 Pew Research poll found that 65% of U.S. adults believe that President Donald Trump was too slow to make major steps to stop the spread of the coronavirus. Let's assume that 0.65 is the population proportion. Suppose random samples of 100 U.S. adults are randomly selected, and the proportion of each sample is found. What is the probability that a random sample of 100 adults have a sample proportion greater than 70%? Round the probability to 2 decimal...

Let's assume that 0.65 is the population proportion. Suppose random samples of 100 U.S. adults are randomly selected, and the proportion of each sample is found. What is the standard error of this sampling distribution? Round the value to 3 decimal places.

Page of 12 Binomial Experiments Previously, we learned about binomial experiments. A binomial experiment consists of n independent trials, each having two possible outcomes: success, and failure. In addition, we define p to be the probability of success in one trial, and x is the number of successes in n trials. The probability of obtaining x successes is denoted P(x). The formula for computing this is P(x) = C:p. (1 - p)"-* In this lesson, we use technology rather than...
