A study is being conducted to monitor how second-level students progress in education and how this is influenced by the economic position of their school. A randomly selected sample of such students who complete the Junior Cycle are identified; they are then categorized by their subsequent education outcome, Category A being little or no further education, to Category E the furthest level of education. The schools they attended are put in groups 1 to 3, with group 1 schools being the most economically disadvantaged, group 3 being the least disadvantaged. The numbers of pupils in each category of school with each type of educational outcome are given in the table in ‘Dataset'. Carry out an appropriate statistical test to determine whether the data support a link between the category of school and educational outcome.
Dataset:
| G1 | G2 | G3 | |
| A | 25 | 21 | 9 |
| B | 23 | 16 | 14 |
| C | 20 | 19 | 21 |
| D | 22 | 16 | 16 |
| E | 30 | 12 | 22 |

A survey conducted by a research team was to investigate how the
education level, tenure in current employment, and age are related
to annual income. A sample of 20 employees was selected and the
same data as in the previous problem were collected. In addition a
multiple linear regression analysis was performed to predict annual
income from the other 3 variables. A portion of the output from the
analysis is shown below.

A survey conducted by a research team was to investigate how the
education level, tenure in current employment, and age are related
to annual income. The estimated multiple linear regression equation
that can be used to predict the annual income given number of years
school completed (Education), length of tenure in current
employment, and age can be written as

An observational study
of a group of students was conducted, and students were classified
in two ways. First, they were each classified as to whether or not
they were FullTime or PartTime. Second, they were
each classified as to which of two colleges they were in,
COS (college of sciences) or CBA (college of business
administration). From that data, the following partial joint
probability table was constructed.

classes and another sample of students who had not used a computer.
The sample mean score for students using the computer was 309 with
a sample standard deviation 29. For students not using computer,
the sample mean was 303 and sample standard deviation was 32.
