When peanuts are packaged in their shells, most shells have two peanuts inside, but some have three and some only have one. A qu

Oduvanchick [21]

Answer:

H0: p = 0.1 and Ha: p > 0.1

Step-by-step explanation:

At the null hypothesis, we test if the mean or proportion is equal to a certain value.

At the alternate hypothesis, we test if the mean or proportion is less than, more than, or different of the value tested at the null hypothesis.

A quality control inspector wants to determine if more than 10% of all shells contain just one peanut.

The value of 10% = 0.1 is tested, which means that the null hypothesis is $H_{0}: p = 0.1$

Test if it is more than 10% = 0.1, so the alternate hypothesis is: $H_{a}: p > 0.1$
