Apopulation is normally distributed with µ = 100 and σ = 10. a sample of size 9 is selected. the probability that an individual value (from this population) falls between 90 and 110 will be the probability that the sample mean (of this sample) falls between 90 and 110.

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)
