... Suppose you incorrectly used the normal distribution of find the maximum error of estimate for the given values of c, s, and n. 1. Find the value of E using the normal distribution. 2. Find the correct value using a t-distribution. Compare the results. c = 0.95, s = 5, n = 16 6.2: Question 6 Suppose ...

... 2. State the alternative hypothesis, H1. For example, that the same population mean is not equal to (≠), greater than (>), or less than (<) the same constant (c) used in H0. 3. Choose the level of statistical significance, . This stipulates the acceptable risk of a Type 1 error (rejecting H0 when H ...

... Since the standard deviations are approximately equal, the number of degrees of freedom is n1 + n2 – 2 = 10 + 12 – 2 = 20. The critical t-value for a 90% confidence interval with 20 degrees of freedom is tcrit = ±1.7247. The limits of the confidence interval are then calculated from: ...
