1.1. From previous research, Marta has found that in general there is a 15% chance that any given customer ordering food at her restaurant will choose a salad.  She wants to test whether people are more inclined to eat salads when it is sunny out.

(i) Clearly defining the value of the population parameter ($p$), state a suitable null hypothesis that Marta could use for this test.

(ii) State a suitable alternative hypothesis that Marta could use for this test.

(iii) Give an example of a test statistic that Marta could use to carry out this test.

1.2. After carrying out the test, Marta had evidence to conclude that people are more likely to eat salads when the sun is out. State whether she accepted or rejected the null hypothesis you have written in part (a)(i).
