Answer:
Follows are the responses to this question:
Step-by-step explanation:
0.05 degree of significance for two tail tests and n-1= 9 df, critica t= 2.262
When the absolute value of the test statistic |t| >2.262, the decision rule rejects.
In point c:
It does not reject, because it has the sample that not contradicts the manufacturer's claim
In point d:
For point 1:
The value of p is 0.1880 , that is higher than the 0.05
For point 2:
Yes
I would go with Either E or A
Step 1) Find common denominator. In this case it was 28.
Step 2) Multiply 1/4 by seven to get 7/28 and then 2/7 by 4 to get 14/28.
Step 3) Add numerators: 7+14 to get 21
Step 4) Simpify your new added Fraction 21/28= 3/4
Your answer is 3/4
