The wоrd аssоciаtiоn test, W.A.T., is а brand new untried measure of verbal reasoning. The scores on this type of test usually have a normal distribution but with µ and σ µunknown. An independent random sample of size n=64 yields the following statistics the sample mean, sM =229.2 and Sx =39.7. The designers of the W.A.T. believe that the scores will have mean µ = 240. This may not be true. Find a null and alternative hypothesis to test if the mean value is less than 240 at the α =.05 level of significance. Your answer will be a double (Ho, Ha). Save Your Answer!! For this exam ≠ means not equal.
