Alessandra designed an experiment where subjects tasted water from four different cups and attempted to identify which cup conta

ined bottled water. Each subject was given three cups that contained regular tap water and one cup that contained bottled water (the order was randomized). She wanted to test if the subjects could do better than simply guessing when identifying the bottled water.Her hypotheses were H0: p=0.25H vs.H a :p>0.25H,(where ppp is the true likelihood of these subjects identifying the bottled water).The experiment showed that 20 of the 60 subjects correctly identified the bottle water. Alessandra calculated that the statistic p=20, divided by, 60, 0.3 had an associated P-value of approximately 0.0680.What conclusion should be made using a significance level of α=0.05?A) Fail to reject H0B) Reject H0, and accept HaC) Accept H0​

Calculate the area of the figure. Assume that all angles are right angles.
Nookie1986 [14]
Okay. So I find it easiest to calculate the full area as if the shape was a rectangle, then subtracting open space. We already know that length is 100, so now we just need to find width. 50 + 25 + 50 + 25 + 50 = 200. 200 x 100 =20,000. So now we just need to find the areas of open space and subtract. Both spaces have a length of 75 and a width of 25. 25 x 75 = 1875. There were 2 spaces, and 1875 x 2 = 3,750. 20,000 - 3,750 = 16,250.


The area of the figure is 16,250 feet.
