Two statistics teachers both believe that each has the smarter
class. A summary of the class sizes, class means, and standard
deviations is given below:
n1=12,n2=24,x¯1=86.2,x¯2=77.1,s1=16.7s2=18.8n1=12,x¯1=86.2,s1=16.7n2=24,x¯2=77.1,s2=18.8
Is there evidence, at an α=0.15α=0.15 level of
significance, to conclude that there is a difference in the two
classes? Carry out an appropriate hypothesis test, filling in the
information requested.
A. The value of the test statistic:
B. The degree of freedom for the distribution:
For the next part, it is strongly recommended that you
use the tables provided by the class
C. The approximate range of values for the p-value:
< p-value <
D. Your decision for the hypothesis test:
A. Reject H1.
B. Do Not Reject H1.
C. Reject H0.
D. Do Not Reject H0.
