A Milwaukee television station, WITI-TV, conducted a telephone call-in survey asking whether viewers liked the new newspaper, the Journal Sentinel. On April 26, 1995, Tim Cuprisin, a columnist for the Journal Sentinel, wrote the following comment: "WITI-TV (Channel 6) did one of those polls which they admit are unscientific last week and found that 388 viewers like the new Journal Sentinel and 2,629 didn't like it. We did our own unscientific poll on whether those Channel 6 surveys accurately reflect public opinion. The results: a full 100 percent of the respondents say absolutely, positively not."

Is Cuprisin's comment justified? Explain.
