The minutes to commute to Atlanta college is exponentially distributed with a mean of 20 minutes....
The amount of time Americans commute to work is normally distributed with mean of 45 minutes and a standard deviation of 15 minutes. The 25% of Americans with the LONGEST commuting times all get to work in more than how many minutes? You can use two decimal places of accuracy.
The mean commute time for all commuting students of a university is 23 minutes with a population standard deviation of 4 minutes. A random sample of 63 driving times of commuters is taken. ̅ a) [2pts] Is the sampling distribution of the sample mean ? normal? Circle the number of i. ii. iii. iv. b) the best answer. Yes, because the sample size n is greater than 30. No, because the parent population of the data is not said to...
Estimate your average commute time from your residence to school in minutes. Let this estimated commute time in minutes (30) represent the population mean (μ), and assume a standard deviation (σ) of 7.51 minutes. Then, find the probability for the following scenarios. What is the probability that your commute time is less than 15 minutes? What is the probability that your commute time is greater than 35 minutes? What is the probability that your commute time is between 15 minutes...
The amount of time Americans commute to work is normally distributed with mean of 45 minutes and a standard deviation of 15 minutes. According to the Empirical Rule, approximately 95% of Americans commute between ["20.33", "30", "0", "15"] and ["60", "90", "75", "69.67"] minutes

Assume the commute time is a random variable that follows the normal distribution with a mean of 10.3 minutes with a standard deviation of 4.8 minutes. You wish to calculate the probability that the commute time is more than 16.3 minutes. What is the z value you would look up in the standard normal table to answer this question? What is the probability that the commute time is more than 16.3 minutes? What would be the targeted average commute time...
