URGENT PLEASE HELP PLATO USER The manufacturer of a popular brand of markers is planning to release a new color. To determine which color to add, it mailed out surveys to 5,000 of its customers regarding the general color family they prefer. The returned results are shown in this pie chart.

Based on the results, one member of the management team says they should choose the new color from the blue family of colors since a majority of people prefer those colors.

Another member doesn’t agree and thinks they should do more research. Which statements would support her request?

A majority of the management team prefers the yellow family of colors.
Not all color families were represented in the survey, which could cause a nonresponse bias.
The difference among the percentages is not statistically significant enough to make the claim of majority.
The mail-in survey may have resulted in an undercoverage bias.
Since only existing customers were surveyed, the results were not random.
