Test the claim that the proportion of people who own dogs is less than 33%. A random sample of 1000 people found that 27.8% owned dogs. Do the sample data provide convincing evidence to support the claim? Test the relevant hypotheses using a 1% level of significance. Give an answer to at least 4 decimal places. a. What are the correct hypotheses? (Select the correct symbols and use decimal values not percentages.) H0: H1: Based on the hypotheses, find the following: b. Test Statistic = c. p-value = d. Based on the above we choose to e. The correct summary would be:

You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly less than 0.69. Your sample data produce the test statistic z=−2.7788. Find the p-value accurate to 4 decimal places.

Speed of light In 1882 Michelson measured the speed oflight (usually denoted c as in Einstein’s famous equationE = mc2). His values are in km/sec and have 299,000 subtracted from them. He reported the results of 23 tri-als with a mean of 756.22 and a standard deviation of 107.12.a) Find a 95% confidence interval for the true speed oflight from these statistics.b) State in words what this interval means. Keep in mindthat the speed of light is a physical constant that, asfar as we know, has a value that is true throughout theuniverse.c) What assumptions must you make in order to use yourmethod?
