About 10% of the human population is left-handed. Suppose that a researcher speculates that artists are more likely to be left-handed than are other people in the general population. The researcher surveys 500 artists and finds that 60 of them are left-handed. (a) Define the parameter of interest and give the null value. (b) State the researcher's null and alternative hypotheses. Ho: p Ha: P ? (c) What proportion of the sample of artists is left-handed? p = (d) To calculate a p-value for the hypothesis test, what probability should the researcher calculate? Make your answer specific to this situation. p ? ✪ (e) Choose the formula for the test statistic. The test statistic is = The test statistic is = The test statistic is = = Null Value Null standard error Sample estimate - Null Value Null standard error Null standard error Sample estimate - Null Value The test statistic is 2 = Null standard error The test statistic is 2 = Sample estimate + Null standart error Sample estimate Null standard error
