Four different paints are advertised as having the same drying time. to check the manufacturer's claims, five samples were tested for each of the paints. the time in minutes until the paint was dry enough for a second coat to be applied was recorded. the following data were obtained. click on the datafile logo to reference the data. at the = .05 level of significance, test to see whether the mean drying time is the same for each type of paint. compute the values identified below (to 2 decimals, if necessary). sum of squares, treatment sum of squares, error mean squares, treatment mean squares, error calculate the value of the test statistic (to 2 decimals). the p-value is what is your conclusion?

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
