In 2016, the World Health Organization estimated that theaverage life expectancy at birth worldwide was 72 years[1]. (Thisincludes all countries of the world, not just the countries in thesample.)

Complete the steps below to carry out a one-meanhypothesis test to test the claim that the averagelife expectancy has increased beyond the global average using a 5%significance level.

Let mean = the average life expectancy of a person at birth(globally).

1. State your Null and Alternative Hypothesis symbolically. (Youmay need to copy and paste symbols.)
2. Verify that the conditions of the one-mean hypothesis test aresatisfied.

1. calculate the test statistic and p-value. Round your answer tothe nearest thousandth. Insert the results from the hypothesis testfrom StatCrunch in the space provided.

Test Statistic:

p-value:

1. Determine if you should Reject null hypothesis or fail toreject the null hypothesis. Use the significance level and yourp-value to explain how you made your decision.

1. Using sentences, write your conclusion using the context of theproblem.
