Solution1.Ho: The average life span today is not greater than 72 years.Ha: The average life span today is greater than 72 years.0.052.3. t-test (one-tailed)4. df=n-1df=100-1=99t₁ = 1.66 Tabular value5. Computation using the formula for sample mean compared with population meantc =Substitute the given values in the formulatc(x-μ)√nS=F = 69= 72μn = 100S = 8.9NOW(69-72)√/1008.9tc = -3.376. Decision: Since t computed value of -3.37 is less than tabular value of 1.66.Therefore, we reject our null hypothesis (Ho).7. Formulate conclusion: The average life span today is greater than 72 years. A personality test was administered to 17 males and 12 females in a publicschool.
