A survey determines that mint chocolate chip is the favorite ice cream flavor of 6% of consumers.
--------
Ho: p <= 0.06
Ha: p > 0.06 (claim)
=============
An ice cream shop determines that of 190 customers, 15 customers stated their preference for mint chocolate chip.
p-hat = 15/190 = 0.079
z(0.079) = (0.079-0.06)/sqrt[0.06*0.94/190] = 1.1028
------
p-value = P(z > 1.1028) = 0.1351
=================================
Find the P-value that would be used to determine if the percentage of customers who prefer mint chocolate chip ice has increased at a 5% level of significance.
