Now because the t-distribution if symmetric, everything to the left of a negative value of t is everything to the right of the corresponding positive value of t. So, for example if you get t = -1.76 and have 12 degrees of freedom, the p-value for the “< test” would be gotten by: = TDIST(-t,DF,1) = TDIST(1.76,12,1).

The t distribution with 19 degrees of freedom has 10% of the values either less than –1.729 (left –tail) or greater than 1.729 (right-tail). TDIST(1.729,19,1) = .050012—one tail probability for x = 1.729 (exactly half of two-tail probability). TINV (P, df) Returns the t value with df …

Find the range of values that defines the middle 80% of the distribution of SAT scores (372 and 628). Find the z-scores - -1.28, 1.28. For a normal distribution, find the z-score that separates the distribution as follows: Separate the highest 30% from the rest of the distribution. .52. Separate the lowest 40% from the rest of the distribution. .25

, for a normal distribution with mean = mu. standard deviation = sigma. e.g., NORMDIST (12, 5, 2, 1) = .999767. This is the probability that the random variable is less than or equal to 12 for a normal distribution with mean 5 and standard deviation 2. Note if the last argument is 0, it returns the height of the normal distribution at point . a ...
