ty Theoretical tribution DO AN The Z Distribution pictured above is also known as the Standard Normal Distribution. We can write this as Z ~ N(0,1) which is notation for 'Z is normally distributed with mean = 0 and a standard deviation = 1! In Statkey use the Normal Distribution in 'Theoretical Distributions' to calculate the area in left and right tails more extreme than z = -2.17 & z = 2.17. Give your answer to 3 decimal places. Answer:
= Use the hypotheses Ho: 4 = 57 and Ha: > 57, the sample statistics x = 58.5, SE = 0.783 & StatKey (Theoretical Distributions - Normal) to calculate a p-value. Round your test statistic to 3 decimal places when using StatKey and give your final p-value answer to three decimal places. Hint: You need to consider whether the p-value is in one or two tails of the distribution p-value = (3dp) For an example of how to do a calculation like this see this demo in Excel.
