An experiment employing a randomized block design has 4 treatments and nine blocks, for a total of 4x9=36 observations. Conduct a test at alpha 0.05 to verify whether the block means are equal, knowing that SSTO = 500, SST = 50% of the total Sum of Squares and SSB is = 20% of SSTO. The results of the analysis for block effect are: O F = 2; Rejection region F =2.36 Fail to reject Ho, There is no block effect...

Create a 32-run crossed array design with six control factors and two noise factors such that (1) all control × noise two-factor interactions are clear, (2) all noise main effects are clear, and (3) all noise × noise two-factor interactions are clear. Fully describe the reasoning that you used to create your design.

A study explored the effect of ethanol on sleep time. Fifteen rats were randomized to one of three treatments. Treatment 1 was water (control). Treatment 2 was 1g of ethanol per kg of body weight, and Treatment 3 was 2g/kg. The amount of REM sleep (in minutes) in a 24hr period was recorded: Treatment 1 63 54 69 50 72 Treatment 2 45 60 40 56 Treatment 3 31 40 45 25 23 28 Are these data strong evidence REM...
