The value of t-test statistics used for testing $Ho : \mu =40$ from a sample of 16 observations with sample mean $(\overline{x})=50$ and sample standard deviation (S) = 20, is : |
2 2.5 0.8 0.04 |
2 |
The correct answer is Option (1) → 2 The t-test statistic is, $t=\frac{\bar x-μ_0}{s/\sqrt{n}}$ $=\frac{50-40}{20/\sqrt{16}}=\frac{50-40}{5}=2$ |
