A random sample of 100 recorded deaths in the Philippines during the past year showed an average life span of 71.8 years, with a standard deviation of 8.9 years. Does this seem to indicate that the average life span today is greater than 70 years? Use a 0.05 level of significance (critical value = 1.645). Provide the following: a. Null and Alternative Hypothesis b. The z/t computed value. c. Decision d. Draw the graph
