Has the mean age of the onset of anorexia nervosa in women been decreasing? The precious mean age is 15 years. A sample of 20 women showed a mean age of 14.250 years with a standard deviation of 1.512 years. Construct a 95% confidence interval for the mean age of the onset of anorexia nervosa.

The Huntington’s Disease (HD) gene (HTT) is located on chromosome 4, and the age of onset...

The Huntington’s Disease (HD) gene (HTT) is located on chromosome 4, and the age of onset of the condition is closely related to the repeat-expansion size within this gene. Recent research shows that a particular variant on chromosome 15 acts as a modifier for the condition. Someone with a repeat expansion in their HTT gene as well as this modifier variant will develop HD symptoms approximately six years earlier than someone without this modifier variant. A woman with Huntington’s disease...
