Problem 1

In an experiment to compare the tensile strengths ofI 5 5 different types of copper wire, J 5 4 samples ofeach type were used. The between-samples and withinsamplesestimates of s2 were computed as MSTr 52673.3 and MSE 5 1094.2, respectively. Use the F testat level .05 to test H0: m1 5 m2 5 m3 5 m4 5 m5 versusHa: at least two mis are unequal.

Tuesday, April 4 • Example 12: Sleeping Medication A research concludes that the number of hours of additional sleep by patients using Ambien increased on average by a statistically significant amount , 1.5 hours. What type of error might this be H :0 Ambien has no effect ; aH : Ambien increases sleep on average; rejected null a. This is a correct decision. The researchers concluded a significant increase in the number of hours of sleep, on av
