The company has found that two mixtures, in particular, give higher flare illumination values than the others. Mixture 1 consists of a blend composed of the proportions.40, .10, .42, and .08, respectively, for the four components of the mixture; mixture 2 consists ofa blend using the proportions .60, .25, .10, and .05. Twenty different blends (10 of each mixture)are prepared and tested to obtain the flare-illumination values.

- A study was conducted by researchers to determine if application of duct tape is more effective than cryotherapy (liquid nitrogen applied to the wart for 10 seconds every 2 to 3 weeks) in the treatment of common warts.The researchers randomly divided 40 patients into two groups. The 20 patients Group 1 had their warts treated by applying duct tape to the wart for 6.5 days and then removing the tape for 12 hours, at which point the cycle was repeated, for a maximum of 2 months. The 20 patients in group 2 had their warts treated by cryotherapy for a maximum of six treatments.Once the treatments were complete, it was determined that 17 patients in Group 1 (duct tape) and 11 patients in Group 2 (cryotherapy) had complete resolution of their warts. Conduct a hypothesis test to address the research question whether application of duct tape is more effective than cryotherapy in the treatment of common warts.
