Sample size n1=20 and sample size n2= 23,sample means,standard deviations and variances are known and unequal : a.what is the significance test statistic for checking the difference between two means at 5% level of significance.What are degrees of freedom to be used and the critical value for that statistic including p-value .Please show all the relevant formula. b.If one data set 1 (n=20) claims to be higher than the other (n=2) for a given parameter at 5% significance,show the critical values and the test static formulae to be used for assessing this claim.
