Hypothesis Testing Examples About 10% of the general population is left-handed. A researcher speculates that artists are more likely to be left-handed than people in the general population. The researcher takes a random sample of 150 artists finds that 26 are left-handed. Does this strong evidence that more than 10% are left-handed? Step 1. Define the parameter and write the hypotheses. Step 2. Sketch the sampling distribution that is expected if the null hypothesis is true. Step 3. Put the sample statistic on the sketch, shade the appropriate area and calculate the test statistic and P-value. Step 4. Make a decision and state the conclusion in the context of the problem.

Unformatted text preview: In the U.S. 51.2% of births that are male. Suppose that a random sample of 1000 births in Florida show that 526 were male. Does this give convincing evidence that the male birth rate in Florida is different from the rate in the U.S.? Step 1. Define the parameter and write the hypotheses. Step 2. Sketch the sampling distribution that is expected if the null hypothesis is true. Step 3. Put the sample statistic on the sketch, shade the appropriate area and calculate the test statistic and P-value. Step 4. Make a decision and state the conclusion in the context of the problem....
