Suppose Abby tracks her travel time to work for 60 days and determines that her mean travel time, in minutes, is 35.6. Assume the travel times are normally distributed with a standard deviation of 10.3 min. Determine the travel time x such that 20.05% of the 60 days have a travel time that is at least x. You may find this standard normal distribution table or this list of software manuals useful. Give your answer rounded to two decimal places....
Suppose Abby tracks her travel time to work for 60 days and determines that her mean travel time, in minutes, is 35.6. Assume the travel times are normally distributed with a standard deviation of 10.3 min. Determine the travel time ? such that 22.96% of the 60 days have a travel time that is at least x. x=_____min
Suppose Abby tracks her travel time to work for 60 days and determines that her mean travel time, in minutes, is 35.6. Assume the travel times are normally distributed with a standard deviation of 10.3 min. Determine the travel time ? such that 26.11% of the 60 days have a travel time that is at least ?.
Suppose the time between buses at a particular stop is a positively skewed random variable with an average of 59 minutes and standard deviation of 6 minutes. Suppose the time between buses at this stop is measured for a randomly selected week, resulting in a random sample of n = 38 times. The average of this sample, X , is a random variable that comes from a specific probability distribution. (a)Which of the following is true about the distribution of...
An engineer commutes daily from her suburban home to her midtown office. The average time for a oneway trip is 32 minutes, with a standard deviation of 4.1 minutes. Assume the distribution of trip times to be normally distributed. a) What is the probability that a trip will take at least 35 minutes? b) Find the probability that exactly 4 of the next 5 trips will take at least 35 minutes.
standard deviation of 1 day. The mean incubation time of fertilized eggs is 21 days. Suppose the incubation times are approximately normally distributed with (a) Determine the 14th percentile for incubation times. (b) Determine the incubation times that make up the middle 39% of fertilized eggs. The time required for an automotive center to complete an oil change service on an automobile approximately follows a normal distribution, with a mean of 19 minutes standard deviation of 3 minutes. and (a)...
suppose that the travel time from your home to your office is normally distributed with mean 40 min and standard deviation 7 min. if you want to be 90% certain that you will not be late for an appointment at 1, what is the latest time that you should leave home?
In a recent year, the mean time spent waiting for a heart transplant was 126.7 days, with a standard deviation of 21.6 days. Waiting times were normally distributed. What is the shortest waiting time that would still place a patient in the longest 15% of waiting times? Show your calculation and the answer rounded to the nearest tenth of a day.
Lab Ty Courses The average travel time to work for a person living and working in Kokomo, Indiana is 17 minutes. Suppose the standard deviation of travel time to work is 4.5 minutes and the distribution of travel time is approximately normally distributed. Course Hon Suppose that it is reported in the news that 8% of the people living and working in Kokomo feel very satisfied with their commute time to work. What is the travel time to work for...
1. The patient recovery time from a particular surgical procedure is normally distributed with a mean of 5.9 days and a standard deviation of 2.1 days. What is the probability of spending more than 2 days in recovery? (Round your answer to four decimal places.) 2. The patient recovery time from a particular surgical procedure is normally distributed with a mean of 5.8 days and a standard deviation of 2.4 days. What is the 90th percentile for recovery times? (Round...
