Your group has invented a solar cell that works by applying photosynthesis chemistry to generating hydrogen which is stored for use in a fuel cell. In 10 different regions differing by weather. You set up solar-city installations (using solar cells and lead acid batteries for storage) and your technology comparing the kilowatt hours generated in a month The results are:

region	1	2	3	4	5	6	7	8	9	10
Solar city	1000	1300	1400	700	620	740	920	640	1500	500
Photo fuel	1200	1500	1300	900	780	860	1200	800	2000	650

a. There is a solar.csv on Canvas with the full data you need, calculate a 95% confidence interval to estimate the difference between the two solar power approaches. Do it both assuming the data is paired and assuming it is notb. Test whether there is a significant difference between the amounts generated assuming a normal distribution, use =0.05c. Test whether there is a significant difference assuming that the data is not normally distributed (what distribution do you use???) use =0.05
