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 you do not know the standard deviations for either. However, assume that the variances of the two populations are equal. You obtain a sample of size n1=42 with a mean of x1=85.6 and a standard deviation of SD1=13.1 from the first population. You obtain a sample of size n2=42 with a mean of x2=87.1 and a standard deviation of SD2=8.9 from the second population. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value =
