Q G Test 4 Question 19 of 25 (1 point) | Question Attempt 1 of 1 Time Remaining: 3:31:41 0 Siena V 13 14 15 16 17 18 19 20 21 22 23 24 Espanol Every year, all incoming high school freshmen in a large school district take a math placement test. For this year's test, the district has prepared two possible versions: Version 1 that covers more material than last year's test and Version 2 test that is similar to last year's test. The district suspects that the mean score For Version 1 will be less than the mean score for Version 2. To examine this, over the summer the district randomly selects 6) incoming freshmen to come to its offices to Lake Version 1, and it randomly selects 90 incoming freshmen to come take Version 2. The 6) incoming freshmen taking Version 1 score a mean of 112 5 points with a standard deviation of 14.3. The 90 incoming freshmen taking Version 2 score a mean of 1175 points with a standard deviation of 16.7. Assume that the population standard deviations of the test scores from the two versions can be estimated to be the sample standard deviations, since the samples that are used to compute them are quite large. At the 0.0) level of significance, is there enough evidence to support the claim that the mean test score, Hy, for Version 1 is less than the mean test score, Hy, for Version 27 Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to at least three decimal places. (If necessary, consult a list of formulas.) (a) State the null hypothesis Ho and the alternative hypothesis H,- H : X S (b) Determine the type of test statistic to use. Choose one) (c) Find the value of the test statistic. (Round to three or more decimal places.) X (d) Find the p-value. (Round to three or more decimal places.) (e) Can we support the claim that the mean test score for Version 1 is less than the mean test score of Version 27 OYes ONo
