This is a sample question for a test I am studying for Stats class. Is this a proportion test, a t test or a chi test? Or a Chi fit test? What are the steps for solving this A coin is tossed 1000 times and 540 heads appear. At a= 0.05, test the claim that this is not a biased coin. ( Hint: H0: p = 0.5 versus H1: p 0.5 , not a biased coin means we fail to reject null hypothesis. )
An experiment consists in tossing a coin 3 times. Let X be the number of heads obtained. Then p(X=2) = Give your answer as a fraction (e.g. 1/3 or 5/9 etc.)

For each situation, state the null and alternative hypotheses: (Type "mu" for the symbol u , e.g. mu > 1 for the mean is greater than 1, mu < 1 for the mean is less than 1, mu not =1 for the mean is not equal to 1. %3D Please do not include units such as "mm" or "$" in your answer.) (a) The diameter of a spindle in a small motor is supposed to be 6.5 millimeters (mm) with a standard deviation of 0.18 mm. If the spindle is either too small or too large, the motor will not work properly. The manufacturer measures the diameter in a sample of 15 spindles to determine whether the mean diameter has moved away from the required measurement. Suppose the sample has an average diameter of 6.39 mm. Ho: Ha: (b) Harry thinks that prices in Caldwell are lower than the rest of the country.
