experiment started off with the administer wearing gloves and ask the test subject to close their eyes so slimily seeing it would not help determine which product is which. Then the test subject was asked to draw a number from a box and if it had a zero the administer would give brand j then k but if it was a one they would give brand k the j. Then the experiment move to actually tasting the product which would be a drink‚ and they would take product in the order that the test subject drew. After

85.36 minutes The distribution of sample means will be normal if either the population is normal or if the sample size is greater than 30. Increasing the alpha level (for example‚ from α=0.01 to α= 0.05) Increases the probability of a Type I error. Increases the size of the critical region. Increases the probability that the sample will fall into the critical region. Samples of size n = 16 are selected from a population with μ= 80 with σ= 16.
