Solution Steps

Step 1: Divide the figure into simpler shapes

The figure can be divided into a large square with side length 20 cm and a quarter circle with radius 10 cm.

Step 2: Calculate the area of the square

The area of a square is side * side. The area of the large square is 20 cm * 20 cm = 400 cm².

Step 3: Calculate the area of the quarter circle

The area of a circle is π * radius². The area of the quarter circle is (1/4) * 3.14 * 10 cm * 10 cm = 78.5 cm².

Step 4: Subtract the area of the quarter circle from the area of the square

The quarter circle is cut out from the square, so the area of the figure is 400 cm² - 78.5 cm² = 321.5 cm².

Final Answer

321.5 cm²

A travel analyst claims that the mean room rates at a three-star hotel in Chicago is greater than 152. In a random sample of 36 three-star hotel rooms in Chicago, the mean room rate is 160 with a population standard deviation of 41. At α=0.10, can you support the analyst's claim using the p value? Claim is the alternative hypothesis, fail to reject the null hypothesis as p-value ( 0.121 ) is not less than alpha (0.10), and cannot support the claim
