The time it takes Alice to commute to UCSD is a Gaussian random variable X with a mean of 30 minutes and a standard deviation of 3 minutes. a. What is the probability that Alice’s commute to UCSD takes at least 36 minutes? P X > 36 = b. With probability 0.9, Alice’s commute to campus takes more than 30− ∆ minutes but less than 30 + ∆ minutes. What is the value of ∆? ∆ = Note: In this problem, it is OK to provide approximate answers. Use the table of Φ(·), which is the CDF of the standard Gaussian random variable, given on the next page.

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...
