Solution

The p-value is the probability of 18 or more of the 260 customers preferring mint chocolate chip when 6% of consumers prefer mint chocolate chip.

From Excel, we can find this using

1 -binomdist(19,260,.06,TRUE) = 0.1540 As .1540 > .05,

we do not reject the null hypothesis that the percentage who prefer mint chocolate chip ice cream has remained the same.
