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 29.46% 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....

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.

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...
Suppose the time between buses at a particular stop is a positively skewed random variable with...
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...

Amy has two ways to travel from her home in Norco to her office in Los Angeles. One is to go via the 10 Freeway, and the other is to go via 60 Freeway. In order to determine which way she should travel on a daily basis, Amy has recorded the travel times for samples of ten trips via the 10 Freeway and ten trips via the 60 Freeway. The following table gives the travel times in minutes) for the...
