(b) Sample statistic is 1.6
Explanation:
(a) A null hypothesis is a statement from a population parameter which is either rejected or accepted (fail to reject) the upon testing. It is expressed using the equality sign.
An alternate hypothesis is also a statement from a population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected. It is expressed using any of the inequality signs.
