Answer:
a. the Student's t-distribution with 124 degrees of freedom
Step-by-step explanation:
We have no information about the standard deviation of the population, just for the sample, which means that the student's t-distribution is used.
Degrees of freedom
Sample size subtracted by 1.
125 households were sampled.
125 - 1 = 124 degrees of freedom.
So the correct answer is:
a. the Student's t-distribution with 124 degrees of freedom

Step-by-step explanation:
Answer:
A. false
B. true
C. true
D. false
step-by-step:
A: probability of spinning a 4 on spinner A is 1/4 and probability of spinning a 4 on spinner B is 1/3.
B: there are 2 fours out of 6 possible options so that makes it 2/6, simplify that, it becomes 1/3.
C: 2 and 4 are even numbers so that makes 2/4 possible on spinner A. simplify 2/4 and that becomes 1/2.
D. spinning a 3 on spinner A would make it 1/4 (already simplified). spinning a 3 on spinner B would make it 1/6 (already simplified) therefore spinner A is greater.
