You wish to test the following claim (H) at a significance level of a = 0.10. H₂:1 = 42 Ha: 1 2 You believe both populations are normally distributed, but you do not know the standard deviations for either. However, DON'T assume that the variances of the two populations are equal. You obtain a sample of size n₁ = 16 with a mean of 1 = 78.9 and a standard deviation of SD₁ = 11.9 from the first population. You obtain a sample of size m2 = 25 with a mean of 2 = 87.7 and a standard deviation of SD2 = 19.4 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 = The p-value is... O less than (or equal to) a greater than a This test statistic leads to a decision to... O reject the null O accept the null O fail to reject the null
