Suppose the distribution of weekly study times among FIU students has mean 20 hours and standard deviation 8 hours.
1. In the sample of size 75, determine the probability that the average study time is more than 18.5 hours. Write your answer as a decimal rounded to 3 digits.
2. Would the answer to question 1 still be valid even if the population of study time was skewed?
3. Would the probability in question 1 increase, decrease or stay the same if you had selected a sample of size 250 instead of 75?
