Decimal value data types such as float and double represent the
decimal number as an approximation. In other words, float or double
arithmetic do not give exact answer but near approximation to the
answer. As an example, run the following program and check its
result:
#include <iostream>
using namespace std;
int main()
{
float x= 0.1 * 7; if (x == 0.7)
cout<< "TRUE. \n"; else
cout<< "FALSE. \n"; return 0;
}
In some situations, we need our programs to...
Test the given claim. Use the P-value method or the traditional
method as indicated. Identify the null hypothesis, alternative
hypothesis, test statistic, critical value(s) or P-value,
conclusion about the null hypothesis, and final conclusion that
addresses the original claim.
The mean resting pulse rate for men is 72 beats per minute. A
