Q1 chosse 3 options which are correct
1) a symetric data set must have an odd number of modes
2) A symetric data set cannot have more than one mode
3) the median and interquartile range are measures of location in a set of data
4) the standard deviation and range are measures of dispersion in a set of data
5) interquartile ranges and more resistant to outliers in a set of data than is standard deviation
6) the mean is more resistant to outliers in a set of data than is median
7) In general, the mean is greater than median for right skew data
8) In general, the median is less than mean for right skew data

Q2 choose two options that give the upper quartile and upper adjacent value for data set below
2 4 8 6 3 9 8 11 20

An object is propelled vertically upward from the top of a 112-foot building.
The quadratic function s(t) = -16t² + 176t + 112 models the ball's height above the ground, s(t), in feet, t seconds after it was thrown.
How many seconds does it take until the object finally hits the ground? Round to the nearest tenth of a second if necessary.

The company that Amy works for specifies that the mean must be 100 and the standard deviation must be 10 for a set of data. However, when she measures the values for the actual data, she finds that the mean is 106.5 and the standard deviation is 8.4. What does she have to do to the set of data to make it fit the company's criteria?
