1 What are the steps for hypothesis testing? 2 Calculate a z score for the following raw scores: 13, 15, 17, 18, 14, 19. These are pie data collected by asking 6 different people what their favorite number is out of of 50 people . It is a survey or sample, not population data. First, find the mean (or average of the data.) Type the data into Excel cells. Use =AVERAGE() to find the mean of the data. Next, find the standard deviation by using =STDEV.5() Now use the transformational equation to transform each number into a z score: Z = (x - mean ) / standard deviation 3 All research starts with a problem restated in the form of a 4 The is a statement about the population that either is believe to be true or is used to put forth an argument unless it can be shown to be incorrec beyond a reasonable doubt. 5 Step one in hypothesis testing is: Assume the null hypothesis 6 With a normal curve _ % of the area lies between -1 and 1 standard deviation o (See the Standard Normal Curve illustration on the Normal Curve tab on the Excel s 7 With a normal curve 9% of the area lies between -2 and 2 standard deviations (See the Standard Normal Curve illustration on the Normal Curve tab on the Excel s probability only measures one outcome 9 State the multiplication rule for probability: 10 State the addition rule for probability
