Calculate the test statistic (Round your answer to three decimal places.) Calculate the p-value. (Round your answer to four decimal places.) p-value What is your conclusion? O Do not reject H. We can conclude that there is a significant difference between the population mean scores for the math test and the writing test. Do not reject Hg. We cannot conclude that there is a significant difference between the population mean scores for the math test and the writing test. Reject Ho: We can conclude that there is a significant difference between the population mean scores for the math test and the writing test. Rezect Ho. We cannot conclude that there is a significant difference between the population mean scores for the math test and the writing test.
Calculate the test statistic (Round your answer to three decimal places.) Calculate the p value. (Round your answer to four decimal places.) D-valuta What is your conclusion Do not reject Hy we can conclude that there is a significant difference between the population mean scores for the math test and the writing test. Do not reject My We cannot conclude that there is a significant difference between the population mean scores for the math test and the writing test Reject H: We can conclude that there is a significant difference between the population mean scores for the math test and the writing test. O Reject No. We cannot conclude that there is a significant difference between the population mean scores for the math test and the writing test (b) What is the point estimate of the difference between the mean scores for the two bests? (use math score-writing soone.) What are the estimates of the population mean scored for the two texts? Math writing Which test reports the higher mean score? The math test reports Vimean score than the writing test
A standardized com consists of three parts: math, writing, and critical reading Sample data showing the math and writing scoret for a sample of 12 students who took the exam follow Maths Writing Student 1 540 474 2 3 380 3 52 463 4 574 006 3 16 503 526 130 400 459 9 609 10 373 541 11 390 335 12 595 513
to Use a 0.05 level of significance and test for a difference between the population mean for the math of the population mean for the writing scores (Use math or writing score Formate the hypotheses O Moyo WANSO Moyo OMSO MD o Moyo MO O- HUMO Calculate the test statistic Clound your to three deomal Mate Calculate the wound out to four drome place) DAVE What is your concion? Do not reject No We can conclude that there is an interence between the peption menores for the math and the west Do not reject we cannot endude that there cant erence between the population mean scores for the matter and the whole Reject we can conclude that there cant difference between the population memories for the math test and the writing test Reet Het conclude that there is a contence between the population means for the math test and the best
(b) What is the point estimate of the difference between the mean scores for the two tests? (Use math score - writing score.) What are the estimates of the population mean scores for the two tests? Math Writing Which test reports the higher mean score? The math test reports a Select mean score than the writing test.
