According to recent research, 34% of Americans have less than $450 in the bank for an emergency. Let be hat p the proportion of people who have less than $450 in the bank for an emergency in a random sample of 91 Americans . Determine the probability that the proportion of people in a random sample of 91 Americans who have less than $450 in the bank for an emergency is within 2% of the population proportion. Round the solution to four decimal places . within 2% of the population proportion)= Box Determine the probability that the proportion of people in a random sample of 91 Americans who have less than $450 in the bank for an emergency is less than the population proportion by 9% or more. Round the solution to four decimal places . P( hat p less than the population proportion by 9\% or more)

An earth-conscious clothing store offers a 15% discount if you bring in a bag full of old clothing to recycle the fabric. The probability that each bag brought in will contain fabric that can actually be recycled is 69%. In a given day, if there are 20 bags of fabric brought in to recycle, calculate the following: Round each answer to 4 decimal places. The probability that at least 9 bags will contain fabric that can be recycled

If the probability that a professor correctly writes a slide is 0.80, what is the probability that at least 6 out of 8 slides are correct? Round your answer to two decimal places. Write your answer as a fraction not as a percentage (i.e. write as 0.38 not as 38%).

Suppose that 72% of Veterinary School graduates who take the licensure exam for their state pass the exam.  Find the approximate probability that at least 75% of 150 randomly sampled people taking the Veterinarian licensure exam will pass the exam.  Round your answer to four decimal places.

Suppose that at a college, 55% of the students earn a degree at the end of four years and 27% earn a degree at the end of five years. What is the probability of earning a degree at the end of four or five years? Give your answer exactly as a decimal (not as a percent).

The mean percent of childhood asthma prevalence in 43 cities is 2.38%. A random sample of 30 of these cities is selected. What is the probability that the mean childhood asthma prevalence for the sample is greater than 2.8%? Interpret this probability. Assume that o = 1.25%.

A company offers guided tours of remote areas of the world. Each tour consists of 20 people. The probability of selling a ticket for any given spot on the tour is 0.86. The costs to the company are approximately the same regardless of the number of people that show up. To offset the risk associated with a tour not filling up, the company purchases a specialized insurance policy. The policy pays 100 for each ticket that is left unsold, up to a maximum of 400. Let P be the amount that the insurance policy pays to the company for a specific tour. Calculate E[P] to the nearest dollar. O 251 O244 O 259 O 267 275
