A researcher wishes to see if there’s an association between gender and the number of cases of mental disorders. She selects a sample of 30 males and 24 females and classifies them according to their mental disorder. The results are shown below. Results Table Gender Anxiety Depression Schizophrenia Total Male 8 12 10 30 Female 12 9 3 24 Total 20 21 13 54 Use a 0.10 significance level to test the claim that there is an association (dependency) between gender and the number of cases of mental disorders. State the Null and alternate hypotheses in words. Significance level Find the chi-square test statistic. Find the p-value. State the decision State the conclusion

In this prоblem, yоu аre tаsked with cаlculating the shaded area within a circle, excluding the area оf an inscribed square. You need to print out the final answer of the shaded area to three decimal places. Hints: The radius of a circle is half of its diameter: r=diameter2r = frac{text{diameter}}{2} Use the formula for the area of a circle: Acircle=πr2A_{text{circle}} = pi r^2 Use the formula for the area of a square: Asquare=s2A_{text{square}} = s^2 The shaded area is calculated as: Ashaded=Acircle−AsquareA_{text{shaded}} = A_{text{circle}} - A_{text{square}} Use printf to format the answer to three decimal places.
