Asample of students attending a large university has been selected. is there a statistically significant difference between liberal arts majors and other students on average number of books (other than those required by course work) read per year? use the five step model and write a sentence or two interpreting your results.

liberal arts other

x1= 16.2 x2 = 13.7

s1 = 2.3 s2 = 9.0

n1 = 236 n2 = 321

Since p is less than 0.05, our alpha,  this difference is considered to be extremely statistically significant.

Step-by-step explanation:

Given that a sample of students attending a large university has been selected. Is there a statistically significant difference between Liberal Arts majors and other students on average number of books (other than those required by course work) read per year

Group   Group One     Group Two  

Mean16.20013.700

SD2.3009.000

SEM0.1500.502

N236      321      

(two tailed test)

 The mean of Group One minus Group Two equals 2.500

 95% confidence interval of this difference: From 1.321 to 3.679

Intermediate values used in calculations:

 t = 4.1675

 df = 555

 standard error of difference = 0.600

The two-tailed P value is less than 0.0001

Since p is less than 0.05, our alpha,  this difference is considered to be extremely statistically significant.
