Answer to relevant QuestionsRepeat Exercise 9 assuming that the population standard deviation s is known to be 3.8 chocolate chips. Conduct the hypothesis test using a known value of the population standard deviation σ. For Example 1 in this section, the hypothesis test has power of 0.4274 of supporting the claim that µ < 1.00 W/kg when the actual population mean is 0.80 W/kg. a. Interpret the given value of the power. b. Identify the ...Data Set 21 in Appendix B includes a simple random sample of 37 weights ofpost-1983 pennies.
