Consider a random sample of size 14 from a normal population with expected value μ and variance σ² . Given x̄ = 43.4 and s² = 186, a 95% confidence interval for μ is given by

Expert Solution

Mean = 43.4

Sample size (n) = 14

Confidence interval(in %) = 95

Since we know that

Required confidence interval =

Required confidence interval = (43.4-7.8176, 43.4+7.8176)

Required confidence interval = (35.5824, 51.2176)

A random sample of size n1 = 14 is selected from a normal population with a mean of 74 and a standard deviation of 6. A second random sample of size n2 = 9 is taken from another normal population with mean 70 and standard deviation 14. Let X¯1and X¯2 be the two sample means. Find: (a) The probability that X¯1-X¯2 exceeds 3. (b) The probability that 4.4 ≤X¯1-X¯2≤ 5.4.

Suppose X1, . . . , Xn is a random sample from the Normal(μ, σ2) distribution, where μ is unknown but σ2 is known, and it is of interest to test H0: μ = μ0 versus H1: μ ̸= μ0 for some value μ0. The R code below plots the power curve of the test Reject H0 iff |√n(X ̄n − μ0)/σ| > zα/2 for user-selected values of μ0, n, σ, and α. For a sequence of values of μ,...
