Choose all that would be true. You don't need to actually calculate anything. Think about what you know for mean and median, skew and standard deviation.

• The mean would be higher than the median

• If you added another dot at 105 the mean would for sure go up

• If you added a dot at 120, the range would go up

• The range is 16

• Adding a dot at 40 would increase the Standard Deviation

This bell curve shows a normally distributed data set. Choose all correct statements.

• The mean is 120

• There would be about 95% of data between 90 and 180

• There would be about 16% of data above 180

• The standard deviation is 30

• 50% of this data would be at 150 and above
