10. Professor Snape is your instructor for Chemistry 101. He has given the same final exam for his class for a long time; he happens to know that exam scores on this test are normally distributed and have a population mean of µ=80. Because of prior laboratory catastrophes (don’t worry, all students were returned to their original species), he tried a new method of instruction this year. He got a random sample of n=16 students and taught them using virtual reality. These students then took his original final exam, and their sample average was M=76. --------unique information for the second question below: -------- Assume for this second question that Snape’s final exam has a population standard deviation of σ=6. Can he demonstrate that the virtual reality instruction method was significantly different from his traditional teaching method? (Assume a two-tailed test with α=.05) Yes, he can conclude that his VR method is significantly different from his traditional…

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?
