Age (years) Number of Students (f)

Under 21 416

21-25 420

26-30 219

31-35 51

Over 35 24

Total = 1130

Number of students (f) 416 420 219 51 24 1130

A student from the community college is selected at random. Find the conditional probability that the student is at most 35 given that he or she is at least 26.

Expert Solution

P(student is at most 35 | he or she is at least 26) = P(26-35) / P(at least 26)

= [(219 + 51) / 1130] / [(219 + 51 + 24) / 1130]

= 270 / 294

= 0.9184

After numerous studies, it is estimated that the age of college students follows a normal distribution with a mean of 20.7 years and a standard deviation of 1.8 years. A random sample of 16 college students is taken and the sample mean and sample standard deviation are found to be 21.5 years and 2.5 years, respectively. a. Is the sample average of 21.5 considered an outlier (in other words, what is the chance of getting a sample mean at least...

3. a. A sample of 38 students from a community college reveals the average number of units they are taking is 11.5, with a standard deviation of 1.4. Determine a 98% confidence interval for the true mean. b. Assume now that the same results occurred from a sample of size 9, but it was known that the original population was normal. c. Repeat problem 3a, assuming that the standard deviation was the real population standard deviation.
