Sir could you please solve it step by step

A signal generator is being designed to be used for antenna testing purposes, signal generator is tested with 100 Watts and 150 Watts energy input to see if there is a difference between signal outputs. 100 Watt Energy input 150 Watt Energy input 3 321' 1 337 332.4 2 J 328) 335 3 344.2 347.4 4 327 342.4 5 330.4 339.6 6 340.8 337.4 7 339.2 346.8 8 343 340.4 9 331.8 341.6 10 331.4 345.4 11 344.8 339.2 12 342.0 347.2 13 346.6 349.5 14 334.4 348.9 15 337.5 345.8 16 341.7 338.2 17 347.0 353.6 18 344.7 341.9 19 332.1 341.8 20 337.7 350.9 I 1. Calculate the average signal strengths 311, 312 for two different treatments (100 Watts and 150 Watts) Calculate the sample variances and standard deviations of the two different treatments. 2. Apply hypothesis testing considering that the signal strengths of two mortal formulations are equal. Select a significance level (a) of 0.05 (Hint: Two sample ttest is used for hypothesis testing) 3. Calculate the 98% confidence interval for the difference in signal strengths for the two energy inputs (100 Watt and 150 Watt)
