Answer:
Yes, because the upper limit is less Than 8 minutes
Explanation:
According to the empirical formula :
68.26% of data lies within 1 standard deviation from the mean;
Hence,
Mean ± 1(standard deviation)
The sample mean and sample standard deviation of the given data is :
Sample mean, xbar = Σx / n = 546 / 100 = 5.46
Sample standard deviation, s = 2.475 (Calculator)
The interval which lies within 68.26% (1 standard deviation is) ;
Lower = (5.460 - 2.475) = 2.985
Upper = (5.460 + 2.475) = 7.935
(2.985 ; 7.935)
Since the interval falls within ; (2.985 ; 7.935) whose upper level is less than 8 means patients will have to wait less Than 8 minutes.

Answer:
Following are the code to this question:
CarCounter::~CarCounter()//Defining destructor CarCounter
{
cout << "Destroying CarCounter\n";//print message Destroying CarCounter
}
Explanation:
Following are the full program to this question:
#include <iostream>//Defining header file
using namespace std;
class CarCounter //Defining class CarCounter
{
public:
CarCounter();//Defining constructor CarCounter
~CarCounter();//Defining destructor CarCounter
private:
int carCount;//Defining integer variable carCount
};
CarCounter::CarCounter()//declaring constructor
{
carCount = 0;//assign value in carCount variable
return;//using return keyword
}
CarCounter::~CarCounter()//Defining destructor CarCounter
{
cout << "Destroying CarCounter\n";//print message Destroying CarCounter
}
int main() //Defining main method
{
CarCounter* parkingLot = new CarCounter();//Defining class object parkingLot
delete parkingLot;//
return 0;
}
- In the given C++ language code, a class "CarCounter" is defined, and inside the class, a "constructor, Destructors, and an integer variable" is defined.
- Outside the class, the scope resolution operator is used to define the constructor and assign value "0" in the integer variable.
- In the above-given code, the scope resolution operator, to define destructor and inside this cout function is used, which prints a message.
- In the main method, the class object is created, which automatically calls its class constructor and destructors.
