Answer:
But we need to calculate the mean with the following formula:
And replacing we got:
And for the sample variance we have:
And thi is the best estimator for the population variance since is an unbiased estimator od the population variance
Step-by-step explanation:
For this case we have the following data:
1.04,1.00,1.13,1.08,1.11
And in order to estimate the population variance we can use the sample variance formula:
But we need to calculate the mean with the following formula:
And replacing we got:
And for the sample variance we have:
And thi is the best estimator for the population variance since is an unbiased estimator od the population variance
The answer is 1 and 1/2 feet
Answer:
523.33 cm³
Step-by-step explanation:
Formula of volume of sphere
The volume of the sphere
= 523.33 cm³ (rounded to the nearest hundredth)
No the product will be less than 9/10.
This can be easily seen if the fractions are converted into decimals.
The decimal form of the product of 7/8 and 9/10 is 0.867 while the decimal form of 9/10 is 0.9. Therefore, the product of 7/8 and 9/10 is not greater than 9/10
