I think the answer is C. 1,320
Answer:
a. The probability that 359 or more of 1487 adults sleepwalked is zero (0).
b. Yes, it's significantly higher than the 21.6% of people who sleepwalked.
c. The result suggests 321 adults.
Step-by-step explanation:
a. The assumed 359 sleepwalked adults exceed the 21.6% correct rate. 359 sleepwalked adults give 24.1%.
b. Yes, it is significantly high because it's 24.1% instead of correctly assumed 21.6%.
c. 21.6% sleepwalked adults give 321.2 people. Hence, people can only be in whole of numbers. Therefore, it is 321 adults.

Step-by-step explanation:
