Question

3 (b) Health advisory services state that 50% of heart attack patients die before reaching hospital: the chances of surviving a heart attack are dramatically increased by receiving medical help as quickly as possible. A survey on 240 heart attack victims discovered that men sought help more urgently than women. Men 134 Sample Mean = 3.40, Sample Standard deviation = 1.42 Women 106 Sample Mean = 8.24, Sample Standard deviation = 4.24 Table: Time taken to reach hospital for men and women after initial attack i. Calculate the 95% confidence interval for the difference between the mean times to reach hospital for men and women. ii. Is it possible to infer that there is no difference between the mean times taken to reach hospital from the data given above?
