A recent study found that 61%of workers between the ages of 20-29 cash out their retirement accounts when they lose their jobs or move to a new employer. Complete parts a through e below based on a random sample of 14workers between the ages of 20-29 who lost their jobs or changed employers.
a. What is the probability that exactly 10
workers cashed out their retirement accounts?The probability is nothing.(Round to four decimal places as needed.)b. What is the probability that all 14workers from the sample cashed out their retirement accounts?The probability is nothing.(Round to four decimal places as needed.)c. What is the probability that 11or fewer workers cashed out their retirement accounts?The probability is nothing.(Round to four decimal places as needed.)d. What are the mean and standard deviation for this distribution?The mean is nothing.(Type an integer or a decimal.)The standard deviation is nothing.(Round to four decimal places as needed.)e. Construct a histogram for this distribution. Choose the correct graph below.
