- Use the hypotheses Ho: H = 75 and Ha: u 75, the sample statistics i = 82.5, SE = 3.469 & 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.
N(ug) indicates a normal distribution with a mean, u and standard deviation, o. We can calculate areas in the tails of any normal distribution using StatKey. Open StatKey, go to 'Theoretical Distributions' and choose 'Normal'. You can then use the 'Edit Parameters' button to change the mean and standard deviation as necessary. For the following normal distributions find the probabilities (areas) to the right of 110. N(100,5) Choose... N(100,1) Choose... - N(100,15) Choose... N(100,100) Choose... -
