A sample of size n1 = 16 is taken from a group of bees in one hive, and the sample variance in weight is 1.2 grams. A sample of size n2 = 16 is taken from another hive, and the sample variance is 0.8 grams. What is the estimated standard error for the difference between the two means?

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)

the answer is d
