Terrier weight 9.4 9.9 10.1 7.8 11.2 10.6 10.9 (Ibs) 11.1 7.3 10.1 9.7 10.1 11.3 7.1 Dashund weight 9.7 6.9 7.1 7.8 9.8 (Ibs) 6.8 54 8.2 9.5 Use the sample data shown above to decide whether the mean weight of terriers is different than than the mean weight of daschunds at c = 0.05. 1. The population distribution requirement for this test is: ONone since this is a Z-test ONone since nj and n2 2 30 O Need a normally distributed population since n, and n2 #2 O Ho : P1 2 Pz; Ha : P1 P2 O Ho : /1 = pz; Ha : [1 # #2 O Ho : p1 = Pz; Ha : Pi # Pz 2. This is a O leftO twoO right tailed test and the distribution used is OZ since testing two proportions OZ since both o values are known OT since both o values are not known The Degrees of Freedom (use the simple estimate discussed in the notes, not the messy formula) are ON/A; this is a Z-test O 12 O 14 3. The STS (round to 3 decimals) is: The P-value (round to 4 decimals) is: 4. The decision at a = 0.05 is: O Do not reject Ho since P a Do not reject Ho since P > a
