A University found that 27% of its graduates have taken an
introductory statistics course. Assume that a group of 15 graduates
have been selected.
- Compute the probability that from this group, there are exactly
2 graduates that have taken an introductory statistics course.
- Compute the probability that from this group, there are at most
3 graduates that have taken an introductory statistics course.
- Compute the probability that from this group, there are at
least 4 graduates that have taken an introductory statistics
course.
- Compute the expected number, the variance and the standard
deviation of graduates that have taken an introductory statistics
course.
