For a 95% confidence interval what would the sample size need to be as it's most conservative to have a 2% margin of error

The size of the sample 'n' = 2401

Step-by-step explanation:

Step:1

Given that the margin of error = 2 % = 0.02

The margin of error is determined by

we know that the proportion

Step:2

The margin of error is determined by

              √n  = 49

Squaring on both sides, we get

                n = 49 × 49

                n = 2401

Final -

The size of the sample 'n' = 2401

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)
