A random sample of 100 recorded deaths in the United Arab Emirates 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 with critical region of z > 1.645, state your conclusion if you will accept or reject your null hypothesis. Ho: µ = 70 years H1: µ = 70 years
