Calculate confidence interval mean 50 std 10 n 30
Linear regression, confidence intervals, expected value, and covariance.
Data
Answer
Need 110 on next test
Find the score needed to achieve a 50 average.
Step 1 — Current scores
10, 30
Sum = 40, Count = 2
Step 2 — Equation
(40 + x) / 3 = 50
Step 3 — Solve
x = 50 × 3 − 40 = 110
Score of 110 needed — may exceed maximum if max is 100.
