Low‑density lipoprotein, or ldl, is the main source of cholesterol buildup and blockage in the arteries. this is why ldl is known as "bad cholesterol." ldl is measured in milligrams per deciliter of blood, or mg/dl. in a population of adults at risk for cardiovascular problems, the distribution of ldl levels is normal, with a mean of 123 mg/dl and a standard deviation of 41 mg/dl. if an individual's ldl is at least 1 standard deviation or more above the mean, he or she will be monitored carefully by a doctor. what percentage of individuals from this population will have ldl levels 1 or more standard deviations above the mean? use the 68 – 95 – 99.7 rule.

16% of the individuals from this population will have LDL levels are 1 or more standard deviations above the mean.

Step-by-step explanation:

The 68-95-99.7 rule states that:

68% of the measures of a normally distributed sample are within 1 standard deviation of the mean. 34% of them above, 34% of them below.

What percentage of individuals from this population will have LDL levels 1 or more standard deviations above the mean?

Of the 50% of the measures that are above the mean, 34% are within 1 standard deviation. So 50-34 = 16% are 1 or more standard deviations above the mean.

correct

step-by-step explanation:

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
