Answer: 420.25in^2
Step-by-step explanation:
Area of Square = s^2
20.5^2 = 420.25
Given that

and

, given that the population mean is

and the sample size is n = 16, the test statistic is given by

Since the test is a two tailed test, the p-value is 2(0.07493) = 0.14986
Since the p-value is greater the significant level of α = 0.01, thus, we fail to reject the null hypothesis and conclude that there is no sufficient evidence that <span>the percentage of wheat crop lost to hail in that county is different from the national mean of 11%</span>.
Answer:
the greater the number pf Zeroes after the point, the lower the value of the number, so option 11.003
The percent error is 1,900%
