(a) All variables and other identifiers should have meaningful names. (i) Declare the array used to store the reaction times for the whole school. \_\_\_\_ [1] (ii) Change this declaration so the array can only hold records for a sample of 50 students. \_\_\_\_ [1] (iii) Explain why an array is an effective data structure for storing the reaction time records. \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ [2] (b) Write an algorithm to complete Task 1 for the whole school, using either pseudocode, programming statements or a flowchart. DO NOT include any validation routines. \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ [3] (c)Identify three different types of test data you used to test the validation checks on the age input in Task 1. For each type, give an example of appropriate data. | Type of test data | Example data | | :--- | :--- | | | | | | | | | | [6] (d) Explain how you calculated and outputted the average reaction time based on the user inputs of age and school house, as part of Task 3. Any programming statements used in your answer must be fully explained. \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ [5] (e) Explain how you would change your solution to Task 3 to output the age of the student with the fastest reaction time. \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_
