A study of a new mathematics teaching methodology tested​ students' ability to solve word problems. This table shows how students using the new method and the traditional method performed. What do you​ conclude? (Assume the conditions for inference are met. Assume a significance level of 0.01​.)

Math Problem n Mean SD

New 311 56.9 32.3

Traditional 265 54.3 28.7

Compute the test statistic.

t=___ ​(Round to two decimal places as​ needed.)

Find the​ P-value.

The​ P-value is ____. ​(Round to three decimal places as​ needed.)

State the conclusion.

Answer #1

Fail to reject the null hypothesis. There is not sufficient evidence that students taught using the new method have a different mean score on the word problems test than traditional method.

A college entrance study company determined that a score of 20 on the mathematics portion of the study suggests that a student is ready for​ college-level mathematics. To achieve this​ goal, the company recommends that students take a core curriculum of math courses in high school. Suppose a random sample of 150 students who completed this core set of courses results in a mean math score of 20.3 on the college entrance study with a standard deviation of 3.4 Do...

A random sample of 82 eighth grade students' scores on a national mathematics assessment test has a mean score of 292. This test result prompts a state school administrator to declare that the mean score for the state's eighth-graders on this exam is more than 285. Assume that the population standard deviation is 30. At α=0.14 is there enough evidence to support the administration's claim? Complete parts (a) through (e). a) Write the claim mathematically and identify H0 and Ha....

Using traditional methods it takes 93 hours to receive an advanced driving license. A new training technique using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique on 40 students and observed that they had a mean of 91 hours. Assume the population variance is known to be 25. Is there evidence at the 0.05 level that the technique performs differently than the traditional method? Step 2 of 6: Find the value of the test statistic. Round...
