According to the historical data, the life expectancy in Argentina is equal to the life expectancy in Bolivia. A new study has been made to see whether this has changed. Records of 240 individuals from Argentina who died recently are selected at random. The 240 individuals lived an average of 74.6 years with a standard deviation of 4.6 years. Records of 250 individuals from Bolivia who died recently are selected at random and independently. The 250 individuals lived an average...

Suppose we want to test whether or not three means are equal. We want to perform this test with a 2% significance level. If we perform an ANOVA test, what is the probability of the test producing accurate results (avoiding a Type I error)? Suppose we, instead, run three separate hypothesis tests (t-tests), each with 2% significance level. Mean 1 = Mean 2 Mean 1 = Mean 3 Mean 2 = Mean 3 What is the probability that all three...

a) WHO is examining the improvement in life expectancy in an underdeveloped country. Historical data for the population shows a population mean life expectancy of 58.3 years, and with a population standard deviation of 4.52 years. A recent sample of 75 people produced a sample mean of 60.8 years and a sample standard deviation of 2.84 years. Evaluate H0: μ ≤ 58.3 and HA: μ > 58.3 at a .01 level of significance. b) A medical research team at the...

A group of researchers want to determine if there are any significant differences in life expectancy between smokers and nonsmokers. They test this question with a sample of 62 nonsmokers, where the average life expectancy was 78 years (SS = 2200), and a sample of 50 smokers, where the average life expectancy was 68 years (SS = 2300). Use a confidence interval (where α = .01) for the appropriate statistical test to determine if there is a significant difference in...
