1 b) A research conducted by SSTA022 Class representative at the University of Limpopo indicates that running increases the lifespan among African men. The mean lifespan of 31 African men runners was 34.0% more than the mean lifespan of 31 inactive African men, with variances reported to be 110.25% and 104.04%, respectively. Assuming the populations to be approximately normally distributed with equal variances. 1) Can you conclude that there is a significant increase in the lifespan of the men runners over the inactive men at a = 0.05? ii) Construct a 95% confidence interval for ui- µ₂.
