Please use excel and state the formula used and what was inputted to solve it, thank you 1. A budgeting Web site reported that 20 % of U.S. households have withdrawn money from a 401(k) or other retirement account for needs other than retirement in 2013. A random sample of 11 U.S. households was selected. What is the probability that exactly three households withdrew funds from a retirement account for needs other than retirement? Find the mean, variance, and standard...
According to the Bureau of Transportation Statistics, 81.9% of American Airlines flights were on time in 2017. Assume this percentage still holds true for American Airlines. For the next 46 flights from American Airlines, use the normal approximation to the binomial distribution to complete parts A through D. A. Determine the probability that fewer than 36 flights will arrive on time. (Round to four decimal places as needed.) B. Determine the probability that exactly 32 flights will arrive on time....
According to a flight statistics website, in 2009, a certain airline had the highest percentage of on-time flights in the airlines industry, which was 82.3%. Assume this percentage still holds true for that airline. Use the normal approximation to the binomial distribution to complete parts a through c below. a. Determine the probability that, of the next 30 flights from this airline, less than 22 flights will arrive on time. P(x<22)= (Round to four decimal places as needed.)
The U.S. Department of Transportation recently reported that 80.5% of U.S. airline flights arrived on time. Find the probability that among 12 randomly selected flights, exactly 11 arrive on time. Does that probability apply to one individual who must make 12 flights originating in New York? Explain.
According to a flight statistics website, in 2009, a certain airline had the highest percentage of on-time flights in the airlines industry, which was 81.2%. Assume this percentage still holds true for that airline. Use the normal approximation to the binomial distribution to complete parts a through c below. c. Determine the probability that, of the next 30 flights from this airline, 25, 26, 27, or 28 flights will arrive on time.
According to an airline, flights on a certain route are on time 75% of the time. Suppose 25 flights are randomly selected and the number of on-time flights is recorded (a) Explain why this is a binomial experiment. (b) Determine the values of n and p (c) Find and interpret the probability that exactly 16 flights are on time (d) Find and interpret the probability that fewer than 16 flights are on time (e) Find and interpret the probability that...
A poll reported that 63?% of adults were satisfied with the job the major airlines were doing. Suppose 15 adults are selected at random and the number who are satisfied is recorded. Complete parts? (a) through? (e) below. ?(a) Explain why this is a binomial experiment. Choose the correct answer below. A. This is a binomial experiment because there are two mutually exclusive outcomes for each? trial, there is a fixed number of? trials, the outcome of one trial does...
