Nora, a psychologist, developed a personality test that groups people into one of four personality profiles-A, B,
C, and D. Her study suggests a certain expected distribution of people among the four profiles. Nora then gives
the test to a sample of 300 people. Here are the results:
Profile
A
B
С
D
Expected
10%
40%
40%
10%
# of people
28
125
117
30
Nora wants to perform a xgoodness-of-fit test to determine if these results suggest that the actual
distribution of people doesn't match the expected distribution.
What is the expected count of people with profile B in Nora's sample?
You may round your answer to the nearest hundredth.
