Normal Hypothesis Testing
Assuming the null hypothesis to be true, define the test statistic, usually. Step 4. Calculate either the critical value (s) or the p - value (probability of the observed value) for the test. Step 5. Compare the observed value of the test statistic with the critical value (s) or the p - value with the significance level.
Normal Distribution Hypothesis Tests
Example: Multiple Observations An office water cooler is said by the manufacturers to dispense an average of 250 ml of water each use with a standard deviation of 5 ml. Jordan suspects the manufacturer's claim is too high, and observes the following amounts dispensed over five uses during a day:. 240 ml, 235 ml, 250 ml, 245 ml, 230 ml. Test the manufacturer's claim at the 5\% level.

Finally then, the exam may tell you a sample was taken, tell you the significance level and ask you to perform the rest of the hypothesis test. First, write down the null and alternative hypotheses. Second, write down the distribution for the sample mean. Fourth, compare the test statistic to the critical region. Compare that to the ...

Hypothesis Testing
A hypothesis test is carried out at the 5% level of significance to test if a normal coin is fair or not. (i) Describe what the population parameter could be for the hypothesis test. (ii) State whether the hypothesis test should be a one-tailed test or a two-tailed test, give a reason for your answer. (iii)

The Normal Distribution
The normal distribution is symmetrical about x = μ. Mean = Median = Mode = μ. The normal distribution curve has two points of inflection. x = μ ± σ (one standard deviation away from the mean) There are the results: Approximately two-thirds (68%) of the data lies within one standard deviation of the mean ( μ ± σ)
Normal Distribution
The probability of a single value is always zero for a normal distribution. You can picture this as the area of a single line is zero. P (X = x ) = 0. Your calculator is likely to have a "Normal Probability Density" function. This is sometimes shortened to NPD, Normal PD or Normal Pdf. IGNORE THIS FUNCTION for this course!

Standard Normal Distribution
STEP 1: Sketch the normal curve. Label the known value and the mean. STEP 2: Find the z-value for the given value of x. Use the Inverse Normal Distribution to find the value of z such that or. Make sure the direction of the inequality for Z is consistent with X. Try to use lots of decimal places for the z-value to avoid rounding errors.
Binomial Hypothesis Testing
How is a hypothesis test carried out with the binomial distribution? The population parameter being tested will be the probability, p in a binomial distribution B(n , p); A hypothesis test is used when the assumed probability is questioned ; The null hypothesis, H 0 and alternative hypothesis, H 1 will always be given in terms of p. Make sure you clearly define p before writing the hypotheses
