Area = Length x Width
L = 2.25 m = 225 cm
W = 1.8 m = 180 cm
A = 225 * 180 = 40,500 cm²
Answer: Area of the blanket is 40,500 cm².
I believe the equation is wrong
Answer: 0.670
Step-by-step explanation:
Given that :
Population mean (μ) = 11.5
Sample size, n = 22
Sample mean, x = 11.7
Standard deviation, s = 1.4
The test statistic ;
Tstat = (x - μ) / (s/√n)
Tstat = (11.7 - 11.5) / (1.4/sqrt(22))
Tstat = 0.2 / 0.2984810
Tstat = 0.6700594
Tstat = 0.670 (3 decimal places )
