Ha: The average amount of current passing through a series of

connections is larger than 30 milliamperes (mA).

In symbols,

Ha: ____________

Answer 1

$H_0:$ the average amount of current passing through a series of connections is no more than 30 milliamperes (mA).

$H_a:$ the average amount of current passing through a series of connections is larger than 30 milliamperes (mA).

$H_0:\mu\le30$

$H_a:\mu>30$
