In a standard university class that includes 120 students, mostly non-traditional, the Mean age is 32, with a standard deviation 12 students, and with a normal distribution. Six of these students are international students.
1. What is the probability that, if one student is picked at random he/she be a teenager (12 to 19 years old)? You need to (somewhat) critically think about this before tackling it!

7. At a large university, the mean age of students is 22.3 years, and standard deviation is 4 years. Random samples of 64 students are drawn. (a) What type of distribution is the sampling distribution of mean and why? (b) What is the probability that the average age of these 64 students is greater than 23 years? (c) What is the probability that the total age of a class of 24 students will be less than 540? (5 points)

We assume that the ages of university students are normally distributed. The average age of UAGM students is 26 years with a standard deviation of 3 years. A student is selected at random. What is the probability that you are under 23? What is the probability that you are over 32 years old? What is the probability that he is between 23 and 32 years old?

Students in an introductory statistics class were asked to report the age of their mothers when they were born. Summary statistics include Sample size: 28 students Sample mean: 29.643 years Sample standard deviation: 4.564 years a. Calculate the standard error of this sample mean. b. Determine and interpret a 90% confidence interval for the mother’s mean age (at student’s birth) in the population of all students at this university. c. How would a 99% confidence interval compare to the 90%...
