Please I need help will get max points as many as

194 ft²

Step-by-step explanation:

Area of rectangle R1 = length * width

                                  = 8 * 5

                                  = 40  square feet

Area of rectangle R2 = 14 * 11

                                    = 154 square feet

Area of the figure = 40 + 154 = 194 ft²

You need to perform a chi-square test.

χ² = Σ ( (O-E)² /E

where:
O = observed value
E = expected value
Σ = sum

χ² = (205-175)²/175 + (114-125)²/125 + (264-250)²/250
    = 5.143 + 0.968 + 0.784
    = 6.894

The degrees of freedom are (3-1)=2.

The χ² for DF=2 corresponds to a p-value bigger than 0.025 but smaller than 0.05, while we wanted at least χ²= 5.99 (which is the value for p=0.05).

Therefore, the correct answer is C)Yes, the χ² value was too high
