This class is about Matlab, So you please answer these questions in a full and clear statements with all details and steps in Matlab if needed. 1. (2 points) Execute the following two statements in the MATLAB command window (note that the second statement does not have a semicolon):

days_till_test = 8;

days_till_test < 5

What gets computed by the second statement, and what does it mean (in computer terms and in real-life terms)?

2. (2 points) Next, run the following statement (give a variable named weight the value 100 before running this line).

120 < weight < 150

It appears that the value computed by MATLAB is not meaningful. Show step-by-step how the misleading value was computed by MATLAB.

3. (2 points) Write a logical MATLAB expression to correctly compute the algebraic expression 102 < weight < 150. Your MATLAB expression should produce the correct logical result for any value of weight.

4. (1 point) Assume you have a variable named middle that contains an integer. Write one MATLAB expression that would create an array containing all the integers from middle - 10 to middle + 10, inclusive.

5. (2 points) Suppose you have a variable named total_seconds that represents the number of seconds that have elapsed in some experiment. Write two MATLAB statements that will convert this single value into a time measurement of minutes and seconds. Store the results in appropriately named variables. For example, your code would convert 155 seconds into one variable holding 2 minutes and one holding 35 seconds.

6. (1 point) Name the five variable types found in MATLAB, and give an example of each. In other words, create variables, and assign them a value of each type.
