A mаrine biоlоgist investigаtes whether the meаn bоdy weight of adult sea urchins in a newly established marine reserve has changed from the historical population mean of 24 grams (H0:μ=24, H1:μ≠24). A random sample of n=30 sea urchins yields x¯=25.5 grams and s=3.5 grams. With the population standard deviation unknown, the Stats Kingdom calculator uses a two-tailed t-test at α=0.05, returning t=2.3474, critical values =±2.0452, p-value =0.0259, and df=29. Select all statements that are TRUE.
