1. Draw the dilation of ABCD using center A and scale factor 1/2 label the dilation EFGH 2. Draw the dilation of ABCD using center D and scale factor 1/3. Label the dilation IJKL

3. Show that EFGH and IJKL are similar.

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
