Answer:
Step-by-step explanation:
The null hypothesis is the hypothesis that is assumed to be true. It is an expression that is the opposite of what the researcher predicts.
The alternative hypothesis is what the researcher expects or predicts. It is the statement that is believed to be true if the null hypothesis is rejected.
From the given situation,
Dr. Cawood states that 25% of the beads are purple. This is the null hypothesis.
Oliver, a student in Dr. Cawood's class believes that more than a quarter of the beads in the model box are purple. This is the alternative hypothesis.
Therefore, the correct null and alternative hypotheses are
H0: p = 0.25 and HA: p > 0.25
