WebGetting the p-value from a 1-sample t-test You test 35 cars and discover that the miles per gallon the cars get ranges from 14.4 to 28.8. After putting the data in the column MPG, you perform Minitab’s t-test (the menu command Stat > Basic Statistics > 1-Sample t, or the session command TTEST) and get these results: One-Sample T: C1 WebP-value Calculator. Please provide any one value below to compute p-value from z-score or vice versa for a normal distribution.

Then we will subtract the smaller value from the larger value: 0.8413 – 0.6554 = 0.1859. Thus, the probability that a value in a given distribution has a z-score between z = 0.4 and z = 1 is approximately 0.1859. ipg lightweld cost
