Question

The height of 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 ̸= μ2 at the α = 0.10 significance level. What is the value of the test statistic (TS) and critical value (CV )?
