Correct answer: D. (A)-(III), (B)-(I), (C)-(II), (D)-(IV)
Explanation
H0 : μ = 100 is the null hypothesis stating equality with the hypothesised mean, so (A)-(III). Ha : μ ≠ μH0 is the two-tailed alternative 'not equal to 100', so (B)-(I). Ha : μ > μH0 is the right-tailed alternative 'greater than 100', so (C)-(II). Ha : μ < μH0 is the left-tailed alternative 'less than 100', so (D)-(IV). Hence (A)-(III), (B)-(I), (C)-(II), (D)-(IV).H0 : μ = 100 शून्य परिकल्पना है, जो परिकल्पित माध्य के साथ समानता बताती है, अतः (A)-(III)। Ha : μ ≠ μH0 द्विपुच्छीय वैकल्पिक परिकल्पना '100 के बराबर नहीं' है, अतः (B)-(I)। Ha : μ > μH0 दक्षिण-पुच्छीय वैकल्पिक परिकल्पना '100 से अधिक' है, अतः (C)-(II)। Ha : μ < μH0 वाम-पुच्छीय वैकल्पिक परिकल्पना '100 से कम' है, अतः (D)-(IV)। अतः उत्तर (A)-(III), (B)-(I), (C)-(II), (D)-(IV)।More Research Aptitude questions
