Attached is the Question:

($ 11.3) Consider the following summary statistics, taken on two independent random samples drawn from normally distributed populations: SAMPLE 1 SAMPLE 2 - 5.6644 $5 = 48.5809 $1 - 5.03 52 - 3.84 Using the Welch approximate f procedure for independent samples, test the null hypothesis Ho : #1 - wa against the one-sided alternative HA : #1 > #2 . Calculate the value for the f test statistic. Round your response to at least 2 decimal places. Number (S 11.3) Consider two independent random samples of sizes ny = ff and ny = ff, taken from two normally distributed populations. The sample standard deviations are calculated to be s,= 1.52 and sy = 6.32, and the sample means are $1 = -18.9 and co - -0.898, respectively. Using this information, test the null hypothesis Ho : #1 - 12 against the one-sided alternative HA : #1
