Compute P (X) using the binomial probability formula. The termine whether the normal distribution can be used to estimate this probe result with the exact probability. n = 60,p = 0.2, and x = 20 P (X) = 0.0058 (Round to four decimal places as needed.) Can the normal distribution be used to approximate this probability? A.
WebStep 1: Sketch a normal distribution with a mean of \mu=150\,\text {cm} μ = 150cm and a standard deviation of \sigma=30\,\text {cm} σ = 30cm. Step 2: The diameter of 120\,\text {cm} 120cm is one standard deviation below the mean. Shade below that point. Step 3: Add the percentages in the shaded area: Web20 de mar. de 2024 · Proof: The probability density function of the normal distribution is: f X(x) = 1 √2πσ ⋅exp[−1 2( x−μ σ)2]. (4) (4) f X ( x) = 1 2 π σ ⋅ exp [ − 1 2 ( x − μ σ) 2]. Thus, the cumulative distribution function is: F X(x) = ∫ x −∞N (z;μ,σ2)dz = ∫ x −∞ 1 √2πσ ⋅exp[−1 2( z−μ σ)2]dz = 1 √2πσ ∫ x −∞exp⎡⎣−( z−μ √2σ)2⎤⎦dz.
