Which code computes the sample and population standard deviation of the dataset 3, 5, 5 and 9? Group of answer choices import statistics print('The population standard deviation is: ' str(statistics.stdev([3, 5, 5, 9]))) print('The sample standard deviation is: ' str(statistics.pstdev([3, 5, 5, 9]))) import numpy scores = np.array([3, 5, 5, 9]) pstd = np.std(scores) sstd = np.std(scores, ddof=1) print('The population standard deviation is: ' str(pstd)) print('The sample standard deviation is: ' str(sstd)) import numpy as np scores = np.array([3, 5, 5, 9]) pstd = std(scores) sstd = std(scores, ddof=1) print('The population standard deviation is: ' str(pstd)) print('The sample standard deviation is: ' str(sstd)) import numpy as np scores = np.array([3, 5, 5, 9]) pstd = np.std(scores) sstd = np.std(scores, ddof=1) print('The population standard deviation is: ' str(pstd)) print('The sample standard deviation is: ' str(sstd))
