(a)

Barone argues that there is non-response bias in the surveys because this bias is less of a concern if both groups are assumed to respond at the very same rate. The conservatives tend than other classes to fail to participate.
(b)
To find: the population for the provided surveys.
(b)
Explanation of Solution

(d)
To Explain: the meaning of not statistically significant.
(d)
Explanation of Solution
The few researchers note that there is no statistically significant difference between the opinions expressed in the two surveys. l In this case, the statistically not relevant means difference of sizes and there is no bias and the differences observed are equivalent to the difference that might have been observed simply due to normal variability sampling,
