Question

I need to show the linear regression of this. Y: temperature goes up X: ice cream sales go up

I work in an ice cream shop and it seems as the temperature rises in the summer months so do the ice cream sales. The temperature rising will be my independent variable. (?)

Data:

Month - Average Temp. - Gallons of Ice Cream

January - 25 degrees - 167 gallons

February - 32 degrees - 176 gallons

March - 37 degrees -179 - gallons

April - 50 degrees - 201 gallons

May - 64 degrees - 325 gallons

June - 77 degrees - 575 gallons

July - 82 degrees - 720 gallons

August - 78 degrees -675 gallons

September - 70 degrees - 505 gallons

October - 55 degrees - 315 gallons

November - 41 degrees - 178 gallons

December - 22 degrees - 160 gallons

H_o : ρ= 0

H₁ :ρ =0

The results:

Temperatures: __?__

Ice Cream Sales: __?__

R² = ___?___

r=___?____

Could you please solve this problem for me and correct any mistakes I may have made in writing it out. Thank you!
