Answer:
Dependent.
Quantitative.
Step-by-step explanation:
<u>Determine whether the sampling is dependent or independent.</u>
This is a matched-pair data test, as the same students are measured two times in order to compare the results.
This type of samples are dependent, as they are correlated between them.
<u>Indicate whether the response variable is qualitative or quantitative.</u>
The response variable is the test score. This is a quantitative variable, as this can be defined by a number. Both sample scores are averaged and compared.
45 (price of them) divided by 5 (the amount of tickets) = £9
one ticket = £9
so 9 (the price of one ticket) x 7 (the number of tickets) is £63
the answer is 63.
