Answer:
C. Yes, these statements have two non-overlapping hypotheses and compare a parameter to a value
Explanation:
Hypothesis testing is a statistical method used for accepting or rejecting a statement in statistics. Hypotheses testing are of two types; the null and the alternative hypothesis. The former disproves a particular research statement while the latter (alternative hypothesis) accepts the proof of a statement. When a statement is accepted, it is known as an alternative hypotheses(HA) and when a statement is rejected, it is a null hypothesis (H0)
The statements in question are therefore valid pair of null and alternative hypotheses.
This statements are the hypothesis that compares a parameter to a value as shown;
H0: l = 9
HA: l < 9
H0 and HA are the hypothesis, I is the parameter and 9 is the value.
Based on the above explanation, it can be concluded that the statement above are valid pair of null and alternative hypothesis. They have two non-overlapping hypotheses and compare a parameter to a value.
