A sample of 8 golf balls is randomly selected and the following weights are measured in grams. Give a point estimate for the population variance. Round your answer to three decimal places. 45.15,45.12,45.19,45.08,45.21,45.17 ,45.14,45.24

And the sample variance is given by:

And replacing we got:

And this one is the best estimator for the population variance

Step-by-step explanation:

For this case we have the following data:

45.15,45.12,45.19,45.08,45.21,45.17,45.14,45.24

The first step would be calculate the sample mean given by:

And replacing we got:

And the sample variance is given by:

And replacing we got:

And this one is the best estimator for the population variance

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
