Patty's Parasols recorded the monthly rainfall and their umbrella sales for an entire year. The following table
shows the inches of rainfall and the number of umbrellas the store sold each month. The relationship between
the inches of rainfall and umbrella sales can be modeled using a linear function.
Month
Jan. Feb. Mar. Apr. May Jun Jul Aug Sept. Oct. Nov. Dec.
Rainfall (in.)
3.1 4.0 4.3 3.6 2.4 1.2 0.6 1.5 1.4 1.1 2.6
Umbrella sales 132 140 162 170 156 103 98 87 84 78 110 125
2.5
(a) Using technology, determine the correlation coefficient for the data to the nearest hundredth. Explain
the steps you used.
(b) What does the correlation coefficient for the data indicate about the direction and strength of the
linear association between the monthly rainfall and the number of umbrellas sold?

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:

The brain volumes (cm cubed) of 50 brains vary from a low of 904 cm cubed to a high of 1488 cm cubed. use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 175.5 cm cubed, assuming the estimate is accurate if it is within 15 cm cubed
