There are 5.1090942e+19 different ways this test can be completed
<h3>In how many different ways can this test be completed?</h3>
The given parameters are:
Questions, n =21
Options = 2 i.e. true or false
The number of different ways this test can be completed is calculated as:
Ways = n!
Substitute 21 for n in the above equation.
So, we have:
Ways = 21!
Expand the above equation
Ways = 21 * 20 * 19 * ...... 1
Evaluate the products
Ways = 5.1090942e+19
Hence, there are 5.1090942e+19 different ways this test can be completed

Answer:
chisquare = 31.667
degree of freedom = 2
Step-by-step explanation:
Formula for chisquare test = (O-E)²/E
total number observations= 60 + 25 + 15 = 100
Estimated E,
80% x 100 = 80
15%x100 = 15
5% x 100 = 5
chisquare =
= 5 + 6.67 + 20
= 31.667
from the calculation above the value of the chisquare statistic = 31.67
the degree of freedom is the number of samples in the test n - 1
= 3-1
= 2
I have solve this question also in a tabular form to aid understanding in the file i uploaded.
thank you and good luck!
