0.1356661

Step-by-step explanation:

Let p be the population proportion.

By the given information, we have

Null Hypothesis:

Alternative Hypothesis :

Since , the alternative hypothesis is right-tailed , then the test is a right -tailed test.

Given : Sample size : n= 190

Number of customers stated their preference for mint chocolate chip : 15

The , the sample proportion :

Test statistic for proportion:

i.e  

By using the standard normal distribution table for z-score , we have

P-value for right tailed test :

i.e.

0.1356661

Step-by-step explanation:

A survey determines that mint chocolate chip is the favorite ice cream flavor of 6% of consumers. An ice cream shop determines that of 190 customers, 15 customers stated their preference for mint chocolate chip.
