Final answer:
Part of the question is about an incomplete donation amount to a nursing program, which cannot be answered with the information provided. The second part relates to statistical hypothesis testing, where a null hypothesis concerning the mean salary of registered nurses in California is rejected because a provided p-value is less than 0.05. This does not provide information on the number of students receiving $250 or more.
Step-by-step explanation:
The question you've presented seems to be comprised of two unrelated parts. The initial question about the Sue and Bill Gross School of Nursing receiving a donation is not complete, as the donation amount is missing from the options provided. Therefore, it's not possible to answer whether it's option (a) $50, (b) $100, (c) $200, or (d) $500. However, the additional information provided about a sample of 200 students and the expectation of them receiving $250 or more seems unrelated to the first part and appears to be a statistical question, probably from a hypothesis testing scenario where the mean salary for California registered nurses is tested against $69,110.
In this case, the decision to reject the null hypothesis based on the p-value being less than 0.05 indicates that there is statistically significant evidence to suggest that the average salary is greater than $69,110. However, the information given does not directly answer the question regarding how many out of 200 students would receive $250 or more. This statistic can only be determined if we know the specific distribution of salaries or have some measure of probability associated with the salaries being more than $250.
