government healthcare expenditures‚ as a percentage of gross domestic product‚ on mortality rate per 1000 population in the age group of 15-60. In order to make the estimation results more specific I add the employment rate of females to the initial regression. The estimation is realized using cross sectional data and applying Ordinary Least Squares method. According my estimations there is a statistically significant negative impact of the government expenditures‚ at the same time there is a positive

CASE STUDY: 1 The bulbs manufactured by a company gave a mean life of 3000 hours with standard deviation of 400 hours. If a bulb is selected at random‚ what is the probability it will have a mean life less than 2000 hours? Question: 1) Calculate the probability. Probability is the measure of how an event is likely to occur out of the number of possible outcomes. Calculating probabilities allows you to use logic and reason even with some degree of uncertainty. Find out how you can do the math
