The standard iq test has a mean of 102 and a standard deviation of 13. we want to be 98% certain that that we are within 5 iq points of the true mean. determine the required sample size.

37

Step-by-step explanation:

Margin of error = critical value × standard error

For 98% confidence, CV = 2.326 (from t table).

Standard error is σ / √n, where σ is the population standard deviation, and n is the sample size.

Plugging in:

5 = 2.326 × 13 / √n

n = 36.6

Rounding up, n = 37.
