The sample proportion is the ratio of the number of successes to the total number of samples or trials, Hence, the sample proportion is 0.962

Given the Parameters :

  • Number of successful procedures, x = 152
  • Total number of procedures, n = 158

The sample proportion can be calculated using the relation :

  • Sample proportion = x/n

Sample proportion = 152/158 = 0.962

Hence, the sampling proportion of successful procedures is 0.962.
