Answer:
test statistic= 1.73
the results are not significant
Step-by-step explanation:
Expected probability of all rating= 1/9 or 0.11111
total number of observations= 61+108+47= 216
Observed value for same rating= 61/216= 0.282407
Observed value for Rating differing by one medal= 108/216= 0.5
Observed value for Rating differing by two medal= 47/216= 0.2175925926
Ch- Squared test: Χ²= Σ (O - E)²/ E
O: observed value
E: Expected value
X²= (0.28241-0.11111)²/ 0.1111 +(0.5-0.11111)²/ 0.1111 + (0.21759-0.11111)²/ 0.1111
X²= 1.727 or 1.73
degrees of freedom= 216-1=215
at 0.1 significance and 215 degress of freedom, p-value is 1.0
The result is not significant as p value is greater than 0.1

<u>Answer:</u>
The chance that any single department is chosen for auditing in a given week is 0.04%
<u>Explanation:</u>

Now chance of any single department to be chosen in any particular week will be given by 1 dividing by total no. of departments
which is equal to 1/25
1/25 = 0.04%
which is the chance of percentage of choosing a department
