Short Answer

Simon reads a newspaper report claiming that 12% of all adults in the United States are left-handed. He wonders if 12% of the students at his large public high school are left-handed. Simon chooses an SRS of 100 students and records whether each student is right- or left-handed.

Population for the left-handed students is equal to $0.12$ according to null hypothesis and not equal to $0.12$ according to alternative hypothesis.

Step 1: introduction

Given,

sample size = $100$

left-handed adults in the United States = $12 %$ = $0.12$

Whether each student is right- or left-handed is calculated.

Step 2: explanation

The population = $12 %$ as per the null hypothesis.

$\Rightarrow H_{0} : p = 0.12$

The population is not equal to $12 %$ as per the alternative hypothesis.

$\Rightarrow H_{a} : p \neq 0.12$

Hence, The population of left-handed students is $0.12$ as per the null hypothesis and the population is not equal to $0.12$ as per the alternative hypothesis.
