Two groups of students are given a problem solving a test and the results are compared. Determine whether there is no difference between the means. Use the p value mathod.

mathemetics majors mean = 83.6 s1= 4.3 n1= 36

computer science majors mean = 79.2 s2= 3.8 n2= 36

Step 1

The hypotheses are given below:

Step 2

Step-by-step procedure to obtain the test statistic using MINITAB software:

- Choose
**Stat > Basic Statistics > 2 sample t**. - Choose
**Summarized data**. - In first, enter
**Sample size**as**36**,**Mean**as**6**,**Standard deviation**as**4.3**. - In second, enter
**Sample size**as**36**,**Mean**as**2**,**Standard deviation**as**3.8**. - Choose
**Options**. - In
**Confidence level**, enter**95**. - In
**Alternative**, select**Not equal**. - Click
**OK**in all the dialogue boxes.

Output obtained using MINITAB software is given below:

Step 3

From the output, the test statistic is **4.60** and the p-value is **0.000**.
