16.The height of Iowa corn stalks (in cm) have a N(μ1,σ1) distribution, while the height of Nebraska corn stalks have a N(μ2,σ2) distribution. It is known that σ1 ̸= σ2. A random sample of corn stalks from Iowa and Nebraska yielded the following summary statistics.
Iowa: n1 =15 x ̄1 =155 s1 =16
Nebraska: n2 =17 x ̄2 =145 s2 =10
Suppose we wish to test H0 : μ1 = μ2 versus Ha : μ1 doens't equal μ2 at the α = 0.10 significance level. What is the value of the test statistic (TS) and critical value (CV )?
17. In reference to question (16), which of the following is/are true?
(A) The p − value ∈ (0.02, 0.025)(B) We have evidence that μ1 = μ2(C) There is a significant difference between μ1 and μ2
