Answer:
145°
Step-by-step explanation:
since line BD intercepts the two angles you just add the 2 angles (ABD and DBC) together to get the total of angle ABC
Answer:
Let the 1st group be of students and 2nd group be of faculty.
n1 = 18
\bar{x}_{1} = 8.4
s1 = 7.3
n2 = 15
\bar{x}_{2} = 4.2
s2 = 3.8
1.
H0: =
HA: >
2.
Equality of variance test:
F = s12/s22
= 53.29/14.44
= 3.69
df-num = n1-1 = 17
df-den = n2-1 = 14
p-value = 0..008 < 0.05 i.e.H0 can be rejected and hence we can say that both populations do not have the same variances.
So, test-statistic will be calculated as follows:

3.
df = 26
p-value = 0.0217
4.
E. It confirms the community college results because the p-value is much smaller.
