222 Calls

Step-by-step explanation:

Mean=(∑x)/n

Here n is the total number of values which is 5

Let x_5 be the number of calls for Thornbury

Putting the values of mean and the data given

273=(244+353+235+311+x_5)/5

273*5=1143+x_5

1365=1143+x_5

x_5=1365-1143

x_5=222 Calls

So the number of police calls in Thornbury is 222 ..
