Location Regression Equation Amplitude Wrap Line

1. Syracuse y= 24.1sin(0.5x-2.08)+47.32 24.1 67 47.5

2. Seattle y= 11.68sin(0.54x+-2.35)+53.2 11.68 53

3. Sydney y= 9.44(0.56x+o.68)+63.05 9.44 62.5

Questions

1)The wrap line shows the number around which the data will be. The wrap line is essentially the median of hte data, and it is the middle temperature of each location. The amplitude is amount that teh datat will increase or decrease. For example, each set of data has an amplitude, and it the number is high it means that the data will vary, and the lower it is means that the tmperautre does not change much throughout the year.

2) The three graphs are all in different places in the world, and it makes sense that the data of each is significantly different. In Syraucse and Seattle, the graph shows a sin wave starting lower and gradually getting higher toward the middle, then dreceases. This means that the temperature is lower in the winter months is lower than the temperature is higher in the summer. In Sydney, the grpah shows the opposite, and this proves that the summer is actually colder than it is in the winter.

3) My ideal temperature is 72 degrees. It would make sense to travel to Seattle in July or August because the average temperature is 65, the highest average. The best time to travel to Sydney would be in December, January, or February because that is when the average temperatures are around 71, 72, and 73 degrees.

Looks good so far...keep it up. Wow, the amplitude for Syracuse is 24...that's the most variable weather! We are lucky we get such different seasons.
