Answer:
b. No solution
Step-by-step explanation:
If you subtract the second equation from the first, you get ...
0 = 7
No value of the variable will make this be true. There is NO SOLUTION.
Answer: Option D if we consider the survey as one with only one variable, where the options are "yes, i asisted to more than 4 games" or no.
Step-by-step explanation:
We know that they randomly surveyed 10 students. so the randomization condition was meet, and we know that the students responses were independnt of each other, so options B and C can be discarded.
Now, only 10 students where surveyed, the confidence interval will not be narrow at all.
For example, acccording to StaisticsSolutions, in regression analysis the minimum is actually 10 subjects er variable.
If the researchers are asking the number of games asisted per student, the number of variables will be big, while if the question is "you attended to more than 4 or not?" there is only one variable, then in this case 10 students will be enough.
