Answer

Explanation:

Step1: Find number of male students in French class

Total students taking Spanish or French is 300, and 210 take Spanish. So number of students taking French is $300 - 210=90$. Given 20 females take French, so number of males taking French is $90 - 20 = 70$.

Step2: Find number of female students in Spanish class

210 students take Spanish and 95 are male, so number of females taking Spanish is $210 - 95=115$.

Step3: Calculate row - totals for males and females

Number of male students in total is $95 + 70=165$. Number of female students in total is $115+20 = 135$.

Step4: Complete the two - way table

Spanish French Total
Males 95 70 165
Females 115 20 135
Total 210 90 300

Step5: Calculate percentage of male students in French class

Percentage of male students in French class is $\frac{70}{90}\times100\approx78%$

Answer:

Part A:

Spanish French Total
Males 95 70 165
Females 115 20 135
Total 210 90 300
Part B: 78
