Question

8. निम्नलिखित चाल को किलोमीटर प्रति घंटा में बदले

(क) 5 मीटर प्रति सेकंड ​

Answer 1

Explanation:

Parameters

Population mean = μ = ( Σ Xi ) / N

Population standard deviation = σ = sqrt [ Σ ( Xi - μ )2 / N ]

Population variance = σ2 = Σ ( Xi - μ )2 / N

Variance of population proportion = σP2 = PQ / n

Standardized score = Z = (X - μ) / σ

Population correlation coefficient = ρ = [ 1 / N ] * Σ { [ (Xi - μX) / σx ] * [ (Yi - μY) / σy ] }
