Correct answer: B. Powerशक्ति (Power)
Explanation
The power of a test is the probability of correctly rejecting a false null hypothesis, i.e. rejecting H₀ when the alternative is true. Power = 1 − β, where β is the Type II error. Hence Power.किसी परीक्षण की शक्ति वह प्रायिकता है जिससे असत्य शून्य परिकल्पना को सही रूप से अस्वीकार किया जाता है, अर्थात वैकल्पिक परिकल्पना सत्य होने पर H₀ को अस्वीकार करना। शक्ति = 1 − β, जहाँ β द्वितीय प्रकार की त्रुटि है। अतः शक्ति (Power)।More Research Aptitude questions
