You wish to test the following claim (Ha) at a significance level of =0.10. Ho:1=2 Ha:1<2 you believe both populations are normally distributed, but do not know the standard deviations for either. however, assume that variances of two equal. obtain a sample size n1 =42 with mean x1 =85.6 and deviation sd1 =13.1 from first population. n2 =42 x2 =87.1 sd2=8.9 second what is test statistic this sample? (report answer accurate to three decimal places.) p-value four>
