Given two independent random samples with the following results:n1=18x?1=141s1=13???n2=12x?2=161s2=12
Use this data to find the 98% confidence interval for the truedifference between the population means. Assume that the populationvariances are not equal and that the two populations are normallydistributed.
Step 2 of 3 : Find the margin of error to be used inconstructing the confidence interval. Round your answer to sixdecimal places.
