The cholestetol levels of young women aged 20 to 34 vary with a mean of 185 milligrams per decliter and standard deviation 39 mg/dl. What cholesterol level would be a young woman have in this age group if they were 2 standard deviations below the mean?
185 - (2 * 39) = ?
To find the cholesterol level that is 2 standard deviations below the mean, you can follow these steps:
Step 1: Calculate the value of 2 standard deviations.
Standard deviation = 39 mg/dL
2 standard deviations = 2 * 39 mg/dL = 78 mg/dL
Step 2: Subtract the calculated value from the mean.
Mean = 185 mg/dL
185 mg/dL - 78 mg/dL = 107 mg/dL
Therefore, a young woman in the age group of 20 to 34 would have a cholesterol level of 107 mg/dL if they were 2 standard deviations below the mean.
