Researcher Wants To Compare The Mean Liver Function Levels In Two Populations Individuals Who Consume Alcohol And Those 1 (50.12 KiB) Viewed 24 times

Researcher wants to compare the mean liver function levels in two populations, individuals who consume alcohol and those who do not. The mean liver function levels for those who don't drink is 32 with a standard deviation of 14, with a sample size of 37. The mean liver function levels for those who drink alcohol is 69 with a standard deviation of 19, and a sample size of 38. Construct and interpret a 95% confidence interval that shows the difference in means for those who drink alcohol compared to those who don't. The researchers are 95% confident that the true mean difference in ALT values between the population of drinkers and population of non-drinkers is between 24.22 and 39.78. The researchers are 95% confident that the true mean difference in ALT values between the population of drinkers and population of non-drinkers is between 24.33 and 39.67. The researchers are 95% confident that the true mean difference in ALT values between the population of drinkers and population of non-drinkers is between 24.41 and 39.59. The researchers are 95% confident that the true mean difference in ALT values between the population of drinkers and population of non-drinkers is between 24.32 and 39.68.
