On 2000, 58% of females aged 15 and older lived alone, according to the U.S Census Bureau. A sociologist tests whether this percentage is different today by taking a random sample of 500 females aged 15 or older and finds that 285 are living alone. Is there sufficient evidence at the a = 0.05 level of significance to conclude that the proportion has changed since 2000? a. Name the parameter you are analyzing, along with the appropriate symbol representing this parameter. . Obtain a point estimate for this parameter, along with the appropriate symbol representing this point estimate. State the null and alternative hypotheses. . List the three requirements for performing the hypothesis test. Have the requirements been met? Show your math to receive credit. . Find the test statistic and P-value. Use StatCrunch. Copy and paste your StatCrunch output below. Explain in detail what the test statistic measures, in the context of the problem. Explain in detail what the P-value measures, in the context of the problem. . Use your P-value to make a statistical decision about the null hypothesis (reject or do not reject...). Write a conclusion in context of the problem - a conclusion that a person who has never studied statistics would understand
