Problem 152Multiple Choice

A psychologist suggests that the median number of hours spent reading per week among college students is less than $5$ hours. A random sample of $20$ students reports the following comparison:
$8$ read more than $5$ hours
$10$ read less than $5$ hours
$2$ read exactly $5$ hours
What is the research claim, and what are the correct null and alternative hypotheses?

Claim: median number of hours spent reading per week $is less than 5$ hours

$H sub 0$ : median $equals 5$ hours

$H sub 1$ : median $is less than 5$ hours

Claim: median number of hours spent reading per week $equals 5$ hours

$H sub 0$ : median $equals 5$ hours

$H sub 1$ : median $is greater than 5$ hours

Claim: median number of hours spent reading per week $is greater than 5$ hours

$H sub 0$ : median $is greater than 5$ hours

$H sub 1$ : median $is less than 5$ hours

Claim: median number of hours spent reading per week $is not equal to 5$ hours

$H sub 0$ : median $is not equal to 5$ hours

$H sub 1$ : median $is less than 5$ hours
