Statrek t distribution
WebOn a test whose distribution is approximately normal with a mean of 50 and a standard deviation of 10, the results for three students were reported as follows: Student Opie has a T-score of 60. Student Paul has a z-score of -1.00. Student Quincy has a z-score of +2.00. Obtain the z-score and T-score for EACH student. Show your calculations.

WebSep 2, 2024 · Like a normal distribution, a t-distribution has a bell-shaped curve. The shape of the t-distribution changes when degrees of freedom change. The variance is always greater than one and is equal to v / (v – 2), where v, the degrees of freedom is > 2. As the sample size increases, the t-distribution starts to look more like a normal distribution.
WebBy direct calculation, its mean equals μ and its variance equals ν / ( λ ( ν − 2)). Standardizing it, by construction, creates a distribution of the same shape but zero mean and unit standard deviation. Thus, for the standardized distribution, the formula is the same but we must have μ = 0 and ν / ( λ ( ν − 2)) = 1; that is, λ = ν ...
