Answer:
21.16
Step-by-step explanation:
Starting from the theory we have the following equation:

Using the data supplied in the exercise, we have subtracting the mean and dividing by the standard deviation:

solving for "c", knowing that fi is a tabulating value:

therefore the value of c is equal to 21.16

Answer:</h2>
<u>The pressure will be 176 k Pa</u>
<h2>
Step-by-step explanation:</h2>
Boyle's law states that the product of volume and pressure gives us a constant value so we can write the expression as
P1V1 = P2V2
By arranging the equation we get
P1V1 / V2 = P2
Putting the values
(132 x 20 ) / 15 = P2
P2 = 176 k Pa
