(S 11.3) Consider the following summary statistics, taken on two independent random samples drawn from normally distributed populations: SAMPLE 1 SAMPLE 2 71 = 24 no = 11 = 8.7025 = 40.5769 1 = 5.13 in = 6.32 Using the Welch approximate t procedure for independent samples, test the null hypothesis Ho : A = po against the one- sided alternative HA : /1 > #2 . Calculate the value for the t test statistic. Round your response to at least 2 decimal places. NumberThe P-value is within which one of the following ranges? (Note: This uses a conservative estimate of the degrees of freedom (that is, DF is the lesser of ny - 1 and n2 - 1), so if your calculator value is wrong, you need to use tcdf(t,E99, DF) to get the right P- value.) O P-value > 0.10 0.05
