Some studies have shown that listening to music while studying can improve memory. A researcher obtained a sample of six students and administered a standard memory test while the students were listening to background music. Under normal conditions, ie, without music, µ = 22 and = 3. Scores for the 6 students were: 19, 21, 23, 24, 24, 25. Can the researcher conclude that playing music improved the students’ memory for the material? Use the .05 level.

Solution

Sample mean = 136/6 = 22.67

H0: x bar = mu

Ha: x bar >mu

Right tailed test

Mean differnce = 0.67

Std error = 3/rt 6 = 1.225

t statistic = 0.547

df = 5

p value = .303948.

The result is not significant at p < .05.

No, the researcher cannot conclude that playing music improved the students’ memory for the material
