A researcher was interested in the effects of alcohol on attractiveness of mate selected (referred to as the beer goggle effect). She compared the rating (by independent raters) on level of attractiveness of the partners that young people chose at a party. She compared a group before using alcohol then after using alcohol. Assessment was whether their chosen partners differed in levels of attractiveness. Higher scores indicated more attractive partners. The attractiveness of partner for each participant (measured by independent raters) in 2 scenarios for the same group (before using alcohol and after using alcohol) was as follows:

Before using alcohol	After using alcohol
5	10
12	14
7	15
5	9
8	11
6	10
10	13
8	11
7	9

Test the hypothesis (Use alpha level of 0.05) using both manual and MS Excel calculations that there is no statistically significant difference between alcohol using and non-alcohol using group with regard to the level of attractiveness of the partners they chose by the end of the party. In your answer determine and interpret the strength of this relationship.
