Please help me with this question.

Consider two independent random samples of sizes n, = 10 and 112 = 12, taken from two normally distributed populations. The sample standard deviations are calculated to be 51: 5.1 and 52 =9.0, and the sample means are :51 = '72. .96 and 522 = 80.10, respectively. a) Calculate a point estimate for the difference in population means, #1 p2 . Round your response to at least 3 decimal places. b) Using the Welch Approximate tprocedure and the Welch-Satterthwaite degrees of freedom = 17.867991, what is the appropriate t Q value for a 99% 2 confidence interval? Ftound your response to at least 3 decimal places. c) Calculate the margin of error for a 99% confidence interval, using the Watch Approximate tprocedure. Round your response to at least 3 decimal places
